This is a deep dive into everything worth knowing about the Reformation Sweater in Women’s Size Medium, the Crop Finn Pullover in Alpaca Stretch Knit, finished in that beautiful ivory colorway. We’ll cover the brand, the fabric, the fit, the styling possibilities, and the reasons this particular sweater has earned such devoted fans. By the end, you’ll know exactly why this piece is worth every bit of the attention it receives.
Who Is Reformation and Why Does It Matter?
Before we talk about the sweater itself, it helps to understand the brand behind it. Reformation is a Los Angeles-based fashion label that launched in 2009 with a mission that was, at the time, somewhat unusual in the fashion industry: to make stylish clothing with a meaningful commitment to sustainability. The brand became known for its feminine silhouettes, its vintage-inspired sensibility, and its transparency about the environmental cost of making clothes.
Reformation publishes what it calls a “RefScale” on its products, giving customers a rough sense of how much water, carbon dioxide, and waste went into creating each item. It sources sustainable fabrics, uses recycled and deadstock materials when possible, and has made significant investments in reducing the carbon footprint of its supply chain. This is relevant to the Finn Pullover because the alpaca blend used in this sweater reflects exactly that philosophy — choosing natural fibers with a lower environmental impact than conventional synthetics.
The brand has also developed a reputation for sizing that actually flatters a range of body types, and its knitwear line has become one of its most coveted categories. When Reformation releases a sweater, it tends to sell out quickly, which is exactly why so many shoppers end up searching for pieces like the Finn Pullover on resale platforms like Poshmark, Depop, eBay, and ThredUp.
What Is the Finn Pullover?
The Finn Pullover is a cropped, relaxed-fit sweater designed to sit at or just above the natural waist. The name “Finn” is part of Reformation’s knitwear naming convention, which typically uses simple, clean monikers for its sweater styles. The Finn has a rounded neckline, dropped shoulders, and ribbed detailing at the cuffs and hem that gives it a clean, polished finish without feeling overly structured.
In size medium, the Finn Pullover is intended to fit a range of measurements comfortably, with enough ease that it doesn’t cling in an unflattering way but also enough structure in the knit that it doesn’t look oversized or shapeless. The crop length is deliberate — it’s designed to pair with high-waisted bottoms, which has been a signature pairing in the Reformation aesthetic for years.
The ivory colorway is particularly special. Ivory is not white — it has warmth to it, a slight creaminess that photographs beautifully and flatters virtually every skin tone. It doesn’t carry the starky brightness of pure white, which can sometimes feel harsh or clinical. Instead, ivory feels luxurious, soft, and versatile in a way that makes it easier to build outfits around.
The Fabric: Why Alpaca Stretch Knit Is Something Worth Caring About
The fabric is where this sweater really distinguishes itself. Alpaca fiber is one of the most prized natural textiles in the world, and for good reason. It comes from the fleece of alpacas, animals native to the Andes mountains in South America, and it has properties that make it genuinely superior to many other knit options.
First, alpaca is incredibly soft. It lacks the lanolin found in sheep’s wool, which means it’s naturally hypoallergenic and far less likely to cause the itchiness or irritation that some people associate with wool sweaters. If you’ve ever avoided wool because of sensitive skin, alpaca is frequently the fiber that converts skeptics into believers.
Second, alpaca is lightweight relative to its warmth. The fiber has a hollow core, which means it traps heat exceptionally well without adding bulk. Wearing an alpaca sweater feels like being wrapped in something that weighs almost nothing but keeps you genuinely comfortable across a wide temperature range. It’s warm enough to wear on a crisp autumn day or a mild winter afternoon, but not so heavy that it becomes unbearable the moment you walk indoors.
Third, alpaca has a natural sheen that gives finished garments a beautiful drape and a subtle luminosity. This is part of why the ivory colorway looks so good in this particular fabric — the slight luster of the alpaca fiber makes the ivory glow rather than simply appearing flat.
The “stretch” component of the alpaca stretch knit blend is worth noting as well. Pure alpaca can sometimes feel stiff or lack recovery after wear, meaning it can lose its shape over time. By blending alpaca with a stretch component — typically a small percentage of elastane or a similar fiber — Reformation has addressed this limitation. The result is a sweater that moves with your body, holds its shape wash after wash, and retains the structure of its ribbed detailing over time.
This combination of natural alpaca softness and stretch recovery is what puts the Finn Pullover in a different category than the average knit sweater you might find at a fast fashion retailer. The fabric genuinely feels elevated because it is elevated.
Sizing and Fit: What to Expect in a Women’s Size Medium
Reformation sizing tends to run true to standard US sizing, though some customers note that the brand’s knitwear styles can feel slightly generous in the shoulders due to the dropped shoulder design. In the Finn Pullover, the size medium is typically intended for a bust measurement in the range of approximately 36 to 38 inches and a waist of approximately 28 to 30 inches, though the relaxed nature of the fit means there’s room on either side of those numbers.
The crop length is one of the most important considerations when thinking about fit. The Finn Pullover is designed to hit at or just above the natural waist, which means the hem sits higher than a traditional sweater. For someone with a longer torso, this might mean the sweater hits right at the waistband of high-rise pants or a skirt, creating a seamless, polished look. For someone with a shorter torso, the same sweater might feel a bit more cropped than expected, which can also be styled beautifully — it’s really a matter of knowing how it will land on your specific body.
The dropped shoulders give the sweater a slightly oversized, relaxed feel in the upper body without the garment actually being oversized in a technical sense. The sleeves have a relaxed fit through the arm and taper slightly toward the ribbed cuff. The overall silhouette reads as effortlessly chic rather than aggressively fitted, which is one of the reasons it photographs so well and earns so much social media attention.
If you’re purchasing this sweater secondhand and are between sizes, most styling advice leans toward sizing down rather than up, especially if you want the crop length to feel intentional and the shoulders to sit closer to their designed position.
How to Style the Reformation Finn Pullover in Ivory
One of the defining characteristics of a truly great wardrobe piece is its ability to work in multiple contexts without requiring you to think too hard. The ivory Finn Pullover has that quality in abundance. Here are some of the best ways to wear it.
With High-Waisted Wide-Leg Trousers
This is arguably the sweater’s most natural pairing. High-waisted wide-leg trousers in a neutral — camel, chocolate brown, black, or even a deep navy — create a silhouette that feels simultaneously relaxed and polished. The crop of the sweater sits beautifully at the waistband, and the volume of the wide leg balances the relaxed fit of the knit on top. Add a simple leather or suede loafer and you have an outfit that works for lunch, a gallery visit, or a casual day at a creative office.
With High-Waisted Straight or Slim Jeans
The ivory sweater against a pair of dark wash or medium wash jeans is a timeless combination. The contrast between the soft, creamy knit and the structure of denim creates a visual balance that always looks intentional. Tuck the front of the sweater slightly into the waistband if you want to define your waist more clearly, or leave it untucked for a looser, more relaxed vibe. White sneakers, ankle boots, or pointed-toe flats all work beautifully here.
With Midi Skirts
A midi skirt in a complementary neutral — think chocolate, black, olive, or a soft blush — pairs wonderfully with the Finn Pullover. The length of the skirt creates an interesting proportion against the cropped top, and if the skirt has any texture or movement to it (think pleated satin, flowing crepe, or textured tweed), the simple, clean ivory knit serves as a perfect foil. This combination works especially well for evening occasions where you want to look dressed up without being overdressed.
With Leather or Faux Leather Pants
The softness and warmth of alpaca knit against the sleekness of leather pants is one of those combinations that sounds like it might not work on paper but absolutely does in practice. The tactile contrast between the two fabrics is part of the appeal. Ivory against black leather is especially striking — the light-dark contrast is crisp and modern, and the cozy quality of the sweater prevents the leather pants from feeling too severe.
Layered Under a Coat
Because the Finn Pullover has a relatively simple neckline and a clean silhouette, it layers beautifully under a coat. A camel or tan wool coat worn open over the ivory sweater and straight-leg jeans is a classic combination that never goes out of style. The ivory peeks out from beneath the coat in a way that feels intentional and put-together. Long overcoats, structured blazers, and even denim jackets all work depending on the level of formality you’re aiming for.
As a Transitional Season Piece
One of the most underrated qualities of the Finn Pullover is how well it functions during those in-between seasons — late September through October, or the early days of spring in March and April — when you want warmth but not heaviness. The alpaca knit is warm enough to wear as a standalone top when temperatures are in the 50s and 60s Fahrenheit, and light enough that it doesn’t become oppressive. This kind of seasonal versatility adds enormous value to the piece.
Caring for Your Alpaca Knit Sweater
Alpaca knitwear requires a bit of attention to keep it looking its best, but the maintenance isn’t complicated once you know the basics.
Hand washing is the preferred method. Fill a basin or sink with cool water and a small amount of gentle wool or delicate wash detergent — something specifically formulated for natural fibers. Submerge the sweater gently and allow it to soak for a few minutes before gently pressing (not wringing) the water through the fabric. Rinse with cool water until the water runs clear, then press the excess water out gently by folding the sweater and applying soft pressure. Never wring alpaca — the twisting motion can distort the fibers and cause the sweater to lose its shape.
Lay the sweater flat on a clean towel to dry, reshaping it as needed while it’s still damp. Keep it away from direct sunlight or heat sources, which can cause the fibers to become brittle or the ivory color to yellow over time.
For storage, fold the sweater rather than hanging it. Hanging a knit garment can cause it to stretch out of shape over time due to the weight of the fabric. Store it in a drawer or on a shelf, and if you’re putting it away for the season, a breathable fabric storage bag will protect it from moths and dust.
Pilling is a natural occurrence with any natural fiber knit, including alpaca. A small fabric shaver used gently on any pilled areas will restore the surface of the sweater and keep it looking new. Treat any pilling as routine maintenance rather than a sign of damage, and your sweater will last for many years.
Why This Sweater Holds Its Value on the Resale Market
If you’ve found this sweater listed secondhand and are wondering whether the price being asked is fair, it’s worth understanding why Reformation knitwear tends to hold its resale value particularly well.
The brand’s limited production runs and frequent sell-outs mean that pieces like the Finn Pullover simply aren’t always available at retail, which creates secondary market demand. Buyers who missed a piece during its initial availability are often willing to pay close to retail — and sometimes above retail — for styles they love.
The quality of the fabric also plays a role. An alpaca blend sweater that has been properly cared for genuinely holds up. Unlike cheaper knitwear that begins to degrade after a few washes, a well-maintained Reformation sweater can look almost new years after its original purchase. Buyers on resale platforms understand this, which is why the condition of the garment matters significantly and why sellers who have cared for their pieces can typically command stronger prices.
The ivory colorway specifically tends to attract buyers because it photographs so well and because it’s such a versatile color for styling. Certain neutral shades have an evergreen appeal on the resale market, and ivory in a luxe fiber is one of them.
Final Thoughts: Is the Reformation Finn Pullover Worth It?
Whether you’re buying this sweater at retail, hunting for it on a resale platform, or you already own it and are looking for new ways to wear it, the answer to the question of whether it’s worth it is almost always yes.
What makes a sweater worth owning, ultimately, is a combination of how it feels to wear, how well it integrates with the rest of your wardrobe, how long it lasts, and how often you reach for it. The Reformation Finn Pullover in ivory alpaca stretch knit checks every one of those boxes. It feels genuinely luxurious against your skin. It pairs with practically everything you already own. It holds up beautifully with proper care. And once you own it, you’ll find yourself reaching for it constantly — those are the hallmarks of a piece that earns its place.
The size medium specifically offers a fit that is accessible and flattering for a wide range of body types, and the crop silhouette is versatile enough to be styled modestly or to lean into the contemporary pairing with high-waisted bottoms that has defined so much of recent fashion. The ivory is neither too stark nor too warm — it sits in that sweet spot that makes it genuinely wearable year-round.
This is a sweater that rewards the attention you give it, from how you wash it to how you style it. Find it, keep it, and wear it often. You won’t regret it.
