Plus size shorty knickers from Sans Complexe, designed for your shape
At Sans Complexe Paris, the plus size shorty is designed as a comfortable alternative to thongs and briefs: a fuller cut across the hips and upper thighs that never shows through clothing. Our range runs from UK 10/12 to UK 22/24 (approximate equivalent, please check our size guide), in soft cotton for everyday wear or lace for dressier occasions. As with the whole of our plus size lingerie, every style is chosen to flatter fuller figures without compromising on style.
What's the difference between a shorty and a boyshort?
Shorty and boyshort styles are often confused, but the cut differs noticeably. The plus size shorty covers the hips and sits slightly higher on the thigh, with a leg that's usually cut higher. The boyshort, on the other hand, extends further down the thigh for coverage closer to a short — a good choice if you want extra discretion under a fitted dress. Between the two, the shorty remains the most versatile option: covered enough for comfort, cut high enough to stay feminine.
Which fabric and cut of plus size shorty should you choose?
Cotton shorty for everyday wear
The plus size cotton shorty remains the go-to for daily wear: breathable and soft against the skin, it suits sensitive skin and long days particularly well. We recommend this fabric first for styles worn under looser clothing.
Lace shorty for special occasions
The plus size lace shorty adds a feminine touch without sacrificing comfort, thanks to stretch lace panels that move with your body. Pair it easily with a plus size bra from the same collection to put together a matching set.
Anti-chafing shorty, the solution for thigh discomfort
Its fuller cut across the hips already makes the shorty a more comfortable option than a thong or brief for reducing everyday chafing. For a more targeted need against chafing between the thighs — especially in summer or under a skirt — we'd recommend our dedicated anti-chafing shorts collection, designed specifically for this purpose.
How to choose your plus size shorty size
The right shorty size is determined mainly by your hip measurement, taken at the widest point — not your waist, a common mix-up that explains most discomfort (elastic that rolls, a leg that digs in).
Across our collection you'll find two sizing systems depending on the style: double sizes (38/40, 42/44, 46/48, 50/52 in EU sizing), which offer a bit of flexibility between two close measurements, and single sizes (38, 40, 42... up to 52) on our cotton shorty multipacks, for a more precise fit. Some styles also use an S/M/L/XL labelling, which you can cross-reference against our size guide's conversion table.
If you're between two sizes, always size up: a slightly larger shorty stays comfortable all day, while a too-tight style digs into the skin and rolls at the leg openings, especially in stretch lace. Also keep in mind that the cut affects the fit: a high-waisted style covers the tummy more and can be chosen closer to your actual measurements, while a low-rise, higher-cut shorty is better sized up to avoid compressing the top of the thigh.
For the exact match between your hip measurement and our sizes (38/40 to 50/52 EU), check our underwear size guide before purchasing.
Frequently asked questions: everything about the plus size shorty
Still unsure about the cut, fabric or size? Here are the answers to the questions we get asked most about the plus size shorty.
What's the difference between a shorty and a boyshort?▾
The shorty covers the hips with a higher-cut leg, while the boyshort extends further down the thigh for coverage closer to a short. The shorty remains the most versatile choice between comfort and femininity, ideal for everyday wear and under fitted clothing.
Which shorty prevents chafing between the thighs?▾
The plus size shorty, thanks to its fuller cut, already reduces chafing compared with a thong or brief. For a more pronounced need (summer, skirts, physical activity), our anti-chafing shorts collection offers cuts specifically designed for this purpose.
How do you choose your plus size shorty size?▾
Size is determined by your hip measurement, taken at the widest point. Our range runs from 38/40 to 50/52 (EU sizing), with double or single sizes depending on the style: check our underwear size guide to find your exact match. If in doubt, always size up.
Are there plus size shapewear shortys?▾
Our classic shorty collection focuses on comfort and coverage rather than shaping. For a shapewear effect, our plus size shapewear briefs range is specifically designed to smooth the silhouette under fitted clothing.
Is the plus size shorty suitable for wider hips?▾
Yes — it's actually one of its main strengths. Its enveloping cut without a digging-in elastic makes it a comfortable option for fuller hips, unlike higher-cut styles such as the thong.
