The hunt for a plus size cashmere sweater often ends in frustration: the cut is boxy, the sleeves run short, or the fabric pills after two wears. Real cashmere should drape properly over a fuller frame without clinging or gaping at the buttons. Achieving that balance requires a close look at ply count, fiber length, and sizing charts that actually reflect a curvy silhouette — not just a scaled-up straight size.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing knitwear specifications, from yarn twist and weight per square meter to the construction of reinforced seams, to help buyers separate genuine garment-grade cashmere from flimsy weekend specials.
After sorting through dozens of models and hundreds of verified reviews, I’ve narrowed the field to the seven most reliable options for the plus size cashmere sweaters category based on fit consistency, fiber integrity, and value retention over time.
How To Choose The Best Plus Size Cashmere Sweaters
Cashmere grading varies widely even within the same price tier. A 100% cashmere label doesn’t guarantee a soft, durable garment if the fibers are short or the knit is loose. For plus size fits, the challenge doubles because the fabric must accommodate curves without distorting the stitch pattern.
Ply Count and Fiber Quality
A 2-ply cashmere means two strands are twisted together before knitting — this produces a denser, warmer, and more resilient fabric. Single-ply sweaters feel lighter but tend to pill faster. Look for at least 2-ply construction if you want the sweater to survive more than one season of regular wear.
Plus Size Proportions
True plus size cuts add room across the bust, hips, and upper arms while maintaining a clean shoulder seam. Many brands simply enlarge a standard pattern, which creates excess fabric under the arms and a weirdly short torso. A proper plus size sweater will have a longer body length and wider sleeve openings.
Stitch Density and Weight
Looser knits breathe better but snag easily and lose shape faster. A tight-knit cashmere holds its silhouette, resists pilling, and provides better insulation. For a cardigan, a denser stitch also prevents the front edges from curling or sagging over the course of a day.

In‑Depth Reviews
1. State Cashmere Women’s Essential Crewneck Sweater
This classic crewneck from State Cashmere offers the most reliable balance of softness, weight, and consistent sizing. It’s a 2-ply build, which gives it a denser hand feel than many single-ply alternatives at a similar price. The fiber is smooth against the skin, and the shoulder seams sit properly without riding up — a common failure in scaled-up straight-size patterns.
Reviewers consistently note the rich color saturation, though the navy runs noticeably lighter than the product photos suggest. The cut runs small per multiple reviews, so ordering one size up is recommended, especially for broader shoulders or a fuller bust. The drape is clean, and the hem hits at a flattering hip length without being too long for tucking.
Where this sweater truly stands out is the stitch tension. The tight, even knit resists pilling better than most options in this range, and the fabric holds its shape after repeated wears. For a daily work layer or a weekend staple, this is the most structurally sound pick in the lineup.
Why it’s great
- Dense 2-ply construction for durability
- Classic cut that layers well
Good to know
- Runs small, size up
- Some color variation from photos
2. Jennie Liu Women’s 100% Pure Cashmere Crewneck
Jennie Liu has built a reputation for offering true 100% cashmere at a price that undercuts many designer labels without sacrificing fiber quality. This crewneck features a relaxed silhouette that accommodates a plus size frame without looking slouchy. The shoulder line is softly dropped, which gives extra room across the back without pulling at the chest.
Several reviews highlight the breathable warmth of this sweater — it’s light enough for indoor office wear yet warm enough for a winter walk. The original production run had consistently soft, long-fiber cashmere, but more recent batches have drawn comments about shorter, scratchier fiber. If you buy now, inspect the hand feel immediately and return if it feels rough.
Fit consistency is generally good for sizes up to XL, but the brand doesn’t label extended plus sizes, so bigger frames may find the cut limiting. The relaxed fit works best for those who prefer a little ease without going baggy. For the price, this is a solid entry point into premium cashmere.
Why it’s great
- Relaxed fit with room through the back
- Warm but breathable
Good to know
- Recent batches may have rougher fiber
- Limited plus size range
3. Jennie Liu Women’s 100% Cashmere Button Front Cardigan
This cardigan is a waist-length piece designed for a tailored layering look. The button front features a clean placket that lies flat without gaping, a common problem in plus size cardigans. The fabric is lightweight and soft, with a consistent stitch that doesn’t distort at the buttonholes. Jenny Liu’s construction here is noticeably tighter than their crewneck, which helps the cardigan hold its shape.
Reviewers love the true-to-color red shade, which is vibrant without being loud. However, the length is a potential issue: at waist level, it may feel short on longer torsos or plus size bodies that prefer a hip-length layer. The medium fits a size 8 well, but larger sizes should size up for comfortable buttoning across the bust.
The softness is immediately noticeable out of the package. This cardigan pairs well with high-waisted trousers or a pencil skirt for a refined silhouette. It’s not designed for heavy insulation but serves excellently as a refined indoor layer.
Why it’s great
- No gap at the button placket
- True vibrant color
Good to know
- Waist length may be too short for some
- Not a heavy winter layer
4. State Cashmere Long Sweater Cardigan with Pockets
For those who want a duster-length cardigan without losing cashmere integrity, this is the strongest option. The cut falls well below the hip, providing full coverage that drapes smoothly over a plus size frame. The integrated pockets are set at a practical height and don’t pull the sides out of shape when used.
The knit is moderately dense — not as tight as State’s crewneck, but still substantial enough to resist sagging. Several reviewers note that the color representation is inconsistent: the “tan” or “natural” shade reads as ivory rather than the warm beige shown online. If color accuracy is critical, order the darker hues.
Softness is a consistent strong point. The cashmere feels smooth and has a nice luster. It’s a premium-priced piece, but the long cut, functional pockets, and reputable brand make it a worthwhile investment for daily wear during fall and winter months.
Why it’s great
- Full-length duster cut
- Functional pockets that don’t distort
Good to know
- Color often differs from photos
- Premium price tag
5. Lands’ End Women’s Long Sleeve Open Long Cardigan
Important distinction: this Lands’ End cardigan is made of cotton, not cashmere. It earns a spot here because it offers the best cotton layering option for plus size shoppers who want a similar silhouette without the cashmere fiber cost. The fabric is a medium-weight cotton knit that holds its shape well and doesn’t stretch out at the cuffs.
The fit runs large, which works well for plus size buyers who prefer an oversized, relaxed drape. The long length covers the hips fully, and the open front design with deep pockets feels substantial. Multiple reviews mention that the navy shade is true and the fabric resists fading after washing.
If your goal is a soft, versatile layering cardigan that can handle machine washing without special care, this is a practical alternative. It won’t give you cashmere’s warmth-to-weight ratio, but it delivers on durability and fit consistency for a lower upfront investment.
Why it’s great
- Runs true to size or large
- Machine washable cotton
Good to know
- Not cashmere
- Heavier than cashmere alternatives
6. Style & Republic Women’s 100% Cashmere Turtleneck
Style & Republic offers entry-level pricing for a 100% cashmere turtleneck, making it accessible for shoppers who want the fiber without the high cost. The knit is single-ply, which keeps it lightweight — ideal for layering under a blazer or coat without adding bulk. The turtleneck is snug but not restrictive, and the colors are reported to be rich and accurate to the listing.
The cut runs boxy rather than form-fitting, so if you prefer a closer fit, size down. Several reviews note the fabric is noticeably thin compared to higher-ply options, which raises concerns about long-term pilling. For occasional wear or as an introductory cashmere piece, this is a reasonable choice.
Where it falls short is in density. The fabric is sheer enough that darker bras may show through on lighter colors. The value is there, but you get what you pay for in terms of fiber weight and longevity.
Why it’s great
- Affordable entry into cashmere
- True-to-color shades
Good to know
- Thin single-ply, may pill
- Boxy fit, size down for slim look
7. Chanyarn Women’s 100% Pure Cashmere Turtleneck
Chanyarn’s offering is a pure cashmere turtleneck that delivers a genuinely soft, luxurious hand feel. The fiber is smooth and lightweight, making it comfortable against the skin even for those sensitive to wool textures. The stitch is moderately dense, giving the sweater a polished look that dresses up or down easily.
Fit is the major caveat — multiple customers report that this sweater runs very small. Someone who typically wears a small may need a large to achieve a relaxed fit. This is especially important for plus size shoppers because the cut doesn’t have much stretch or give. If you order, plan to size up by at least two sizes for a comfortable fit.
When you get the sizing right, this is one of the softest options in this list. The turtleneck folds cleanly and stays in place without sagging. It’s a strong runner-up for the value tier, provided you’re prepared to navigate the sizing.
Why it’s great
- Very soft, skin-friendly cashmere
- Smooth, polished knit
Good to know
- Runs at least 2 sizes small
- Limited stretch in the fabric
