What Is a Spencer, and Why Should You Knit One?

Before we get into the specifics of this particular pattern, it is worth pausing to appreciate the garment type itself. A spencer is a short, fitted jacket or top — historically associated with the Regency era, when women wore cropped layering pieces over their high-waisted dresses. The name is said to come from the second Earl Spencer, who wore a similar style after singeing the tails of his coat near a fire and finding the shorter silhouette rather practical.

In the knitting world, a spencer typically refers to a fitted, often cropped knitted top or lightweight layering piece. It sits beautifully over a blouse, under a blazer, or on its own during warmer months. The silhouette is inherently elegant — it nips in at the waist, skims the body without clinging, and has a refined finish that elevates any outfit it is paired with.

The Solstice Spencer by Mandy Julie takes this classic concept and brings it into the present with thoughtful shaping, interesting stitch work, and the kind of construction logic that makes the knitting process itself a pleasure. It is the sort of pattern you look forward to picking up each evening, and the sort of finished object you reach for again and again in your wardrobe.

The Designer: Mandy Julie

Mandy Julie is a knitwear designer whose work is characterized by clean lines, wearable silhouettes, and a genuine understanding of how garments need to fit real bodies. Her patterns tend to prioritize clarity of instruction while incorporating design details that elevate them above the purely functional. She understands that knitters are not just making fabric — they are investing hours of their time and often a meaningful amount of money in yarn, and they deserve a pattern that rewards that investment fully.

The Solstice Spencer reflects her design sensibility perfectly. It is approachable without being simplistic, and ambitious without being unnecessarily complicated. The name itself — Solstice — evokes a sense of balance and turning points, which feels apt for a garment that bridges the gap between seasons and between casual and elevated dressing.

Construction Overview

The Solstice Spencer is typically worked from the bottom up, which gives you a satisfying progression through the body before you tackle the upper portions of the garment. The body is worked flat or in the round depending on the specific instructions in the version you are working from, and the shaping is handled through increases and decreases that create the spencer’s characteristic fitted silhouette.

One of the things that sets this pattern apart is the attention to waist shaping. Many knitted tops can feel boxy or shapeless when finished, but the Solstice Spencer uses carefully placed decreases and increases to create a defined waist that flatters a wide range of body types. The shaping feels gradual and natural rather than abrupt, which means the finished garment drapes beautifully and moves well when worn.

The stitch pattern itself adds visual interest without overwhelming the construction. Depending on which version of the pattern you are working with, you may encounter a combination of stockinette with textural detailing, lace panels, or a subtle stitch that catches the light in a particularly pleasing way. The stitch work is engaging enough to keep experienced knitters interested but not so complex that it becomes stressful to track.

The upper body and yoke area are where the construction becomes especially interesting. The armhole shaping and neckline finishing require careful attention but are clearly explained in the pattern, and Mandy Julie typically includes notes to help you understand the why behind each step — something that is enormously helpful when you encounter a direction that might otherwise feel confusing.

Sleeves, if included in the version you are working, follow the classic set-in or slightly modified armhole approach that complements the fitted nature of the garment. Short sleeves or cap sleeves are common choices for spencers and suit the layering nature of the piece perfectly.

Yarn Choices for the Solstice Spencer

Choosing the right yarn for this pattern is one of the most enjoyable parts of the process and also one of the most consequential. The Solstice Spencer is designed to work with specific yarn weights — check the pattern for the recommended weight and fiber content — but within those parameters, there is a wonderful amount of creative freedom.

Because this is a fitted garment that will be worn close to the body and likely layered, you want a yarn that has good stitch definition, drapes gracefully, and is comfortable against the skin. A smooth, plied yarn in a fingering or sport weight is often ideal for this type of spencer, as it shows off the stitch pattern clearly and creates a fabric with enough structure to hold the shaping without feeling stiff.

Fiber-wise, a merino wool or merino blend is an excellent choice. Merino is soft, breathable, and has enough elasticity to support the fitted shaping of the garment. It also blocks beautifully, which is important for this pattern — blocking will transform your finished piece from something that looks good to something that looks genuinely polished.

If you prefer plant-based fibers, cotton or a cotton-linen blend can work wonderfully for a summer version of the Solstice Spencer. These fibers have less elasticity than wool, so you may want to swatch carefully and consider how the garment will behave when worn over time. A touch of nylon or silk in the blend can add strength and a lovely sheen.

For those who want to push the boundaries a little, a hand-dyed single-ply yarn can create a stunning effect in this pattern, particularly if the colorway is a tonal or semi-solid that allows the stitch pattern to remain legible without competing with the color.

Gauge and Sizing: Getting It Right

Gauge is not something to skip when you are knitting a fitted garment, and the Solstice Spencer is a pattern where achieving the correct gauge genuinely matters. The shaping in this pattern is calculated precisely, and if your gauge is even slightly off, you may end up with a garment that is too small to fit comfortably or so large that all the beautiful waist shaping is lost.

The pattern will specify a gauge — typically a certain number of stitches and rows per four inches of fabric — and you should knit a swatch that is large enough to measure accurately. A common mistake is knitting a small swatch, measuring it, and declaring yourself done. Instead, knit a swatch that is at least six inches square, wash and block it the same way you will treat the finished garment, and then measure it once it has dried completely.

If your gauge does not match, try adjusting your needle size. Going up a needle size will generally loosen your gauge, while going down a needle size will tighten it. Do not be discouraged if it takes two or three swatches to get there — every knitter’s tension is different, and the swatch process is genuinely valuable both for achieving the right fit and for getting to know how your chosen yarn behaves.

The Solstice Spencer is typically available in a range of sizes, and the pattern should include guidance on how to choose the right size based on your measurements. For a fitted garment like a spencer, it is worth taking your measurements carefully and comparing them to the schematic in the pattern rather than relying on your usual clothing size. Pay particular attention to your bust, waist, and hip measurements, as well as the length from your shoulder to your natural waist — these will help you determine both which size to cast on and whether any length adjustments are needed.

Tips for Knitting the Solstice Spencer

Once your gauge swatch is done and your yarn is wound and ready, there are a few practices that will make the knitting process smoother and more enjoyable.

Read through the entire pattern before you begin. This is advice that experienced knitters give constantly, and there is a very good reason for it. Reading through the full pattern allows you to see the logic of the construction, identify any sections that might require extra attention, and avoid being surprised by a direction mid-project. The Solstice Spencer has a satisfying internal logic, and understanding that logic from the start will make each step feel natural.

Keep a row counter or use a simple paper tracker to mark your progress through the shaping sections. Waist shaping involves working decrease rows at specific intervals, and if you lose track of where you are in that sequence, it can be frustrating to figure out where to pick up. A quick note after each shaping row takes only a moment and can save considerable confusion later.

If the pattern includes any lace or textural elements, consider using stitch markers to mark the boundaries of those sections. This makes it easy to verify that you are working the correct stitches in the correct places, especially if you are working in the round.

When you reach the armhole shaping, slow down and pay close attention to the bind-off instructions. Armhole shaping is often the section where knitters encounter confusion, because it involves working partial rows and managing multiple layers of instruction simultaneously. Take it one line at a time, and do not hesitate to recount your stitches after each bind-off row to make sure everything is as it should be.

Blocking and Finishing

The finishing stage of any knitting project deserves as much care as the knitting itself, and the Solstice Spencer is no exception. Once you have completed all the pieces and sewn them together — or if you have knitted in the round and have only minimal seaming to do — blocking will be the step that truly brings the garment to life.

Wet blocking is generally the most effective approach for this type of garment. Submerge the finished pieces or the assembled spencer in cool water with a small amount of wool wash, gently press out the excess water without wringing, and then lay the piece flat on a blocking mat or clean towel. Shape it to the measurements given in the schematic, pin if necessary, and allow it to dry completely before moving it.

The transformation that blocking produces is genuinely remarkable. Stitches that looked uneven while on the needles will even out. The fabric will relax into a beautiful drape. The shaping you worked so carefully will become clearly visible. If you have worked any lace or textural detail, blocking will open it up and allow it to shine.

For seaming, mattress stitch is often the best choice for side seams on a fitted garment, as it creates a nearly invisible join that maintains the clean lines of the spencer. Take your time with seaming — it is one of those skills that improves significantly with practice, and the time invested in a careful, even seam is very visible in the finished piece.

Styling the Solstice Spencer

One of the great pleasures of finishing a Solstice Spencer is discovering how versatile it is as a wardrobe piece. The fitted, cropped silhouette lends itself to a remarkable variety of styling choices.

For a polished, office-ready look, layer the spencer over a crisp white blouse or a silk camisole, pair it with tailored trousers and low heels, and let the knit be the focal point of your outfit. The refined silhouette of the spencer reads as professional without being stuffy, and the texture of the knit adds warmth and depth to an otherwise simple outfit.

For weekend dressing, the spencer works beautifully over a simple t-shirt or tank with high-waisted jeans and ankle boots. The cropped length sits perfectly at the waist of high-waisted bottoms, creating a flattering, elongated look that works for a range of body shapes.

In the warmer months, try wearing the spencer on its own over a midi skirt or wide-leg linen trousers. A yarn in a lighter fiber — cotton, linen, or a silk blend — will keep the garment comfortable in warm weather while still looking polished.

Layering under a blazer or oversized jacket transforms the spencer into an unexpectedly chic underlayer that adds texture and interest to a relatively simple outer layer. The fitted silhouette means it does not add bulk under a jacket the way a bulkier knit might, making it genuinely practical as a layering piece across the cooler months.

Why Knitters Love This Pattern

The Solstice Spencer has developed a devoted following among knitters, and it is not difficult to understand why. It sits in a sweet spot that is genuinely rare in knitwear design: the pattern is interesting enough to keep you engaged through every session of knitting, the construction is logical and well-explained, the finished silhouette is flattering and versatile, and the garment is something you will actually reach for in your wardrobe.

There is also something deeply satisfying about a project that challenges you in just the right way. The Solstice Spencer is not a beginner pattern in the strictest sense, but it is absolutely achievable for a knitter who has completed a few garments and is comfortable with basic shaping techniques. The skills it builds — reading a schematic, working precise shaping, seaming a fitted garment — are ones that will serve you across many future projects.

The community around Mandy Julie’s patterns is also worth mentioning. Knitters who have made the Solstice Spencer tend to be enthusiastic sharers of their process and their finished objects, which means you will find a wealth of photographs, notes, and modifications available to you as you work through the pattern. Seeing how other knitters have interpreted the design in different yarns and colorways is inspiring and useful in equal measure.

From the initial swatch through the final seam, it offers a knitting experience that is thoughtful, engaging, and ultimately deeply satisfying. The finished garment is one that you will wear with genuine pride — a piece that looks handcrafted in the finest sense of the word, elevated and personal and entirely your own.

If you have been on the fence about starting it, consider this your encouragement. Wind your yarn, cast on your swatch, and let the Solstice Spencer become your next great knitting project. The summer solstice, the winter solstice, or any turning point in between — there is never a wrong moment to begin something beautiful.
