Quick answer
Choose the SIN culotte for soft, all-day comfort with delicate leaf embroidery, or the BACK IN BLACK for a modern, nearly invisible look under fitted clothes.
Key differences at a glance
Both briefs are crafted from fine tulle and embroidery, but they serve slightly different wardrobe roles. SIN emphasizes a classic feminine aesthetic with opalescent tulle and leaf-motif sides, while BACK IN BLACK focuses on a clean, modern silhouette with sheer side panels and a no-show edge finish.
Trade-offs to consider
- Comfort vs. invisibility: SIN uses opalescent tulle and folded edges for a soft, all-over comfort that you can forget you're wearing. BACK IN BLACK's clean cut finish is designed to disappear under clothing, but the sheer side panels may feel less substantial against the skin.
- Embroidery coverage: SIN features delicate leaf embroidery on the sides, adding a romantic detail that shows above low-rise bottoms. BACK IN BLACK's embroidery is more concentrated, with a modern transparency effect on the sides that offers a bolder peek-a-boo look. Check your usual waistline height to see how much embroidery will be visible.
- Fit and sizing: SIN is sized in EU equivalents (size 2 = 36/S) and runs true to size for a standard brief fit. BACK IN BLACK's clean cut edge may fit more snugly to stay in place; consider sizing up if you prefer a looser feel.

Best for
