A second-skin layer under your clothes
Merchant copy describes this long-sleeve smoothing tee as made to be worn under clothing for all-day comfort.[1]
Product comparison
Compared within this brand.
| Long-Sleeve Peach-Skin Smoothing T-Shirt: Choose this if you want a fitted long-sleeve crew-neck layering piece in an ultra soft and supple peachskin jersey, made of 80% reprocessed nylon and 20% spandex. It comes in sizes X-Small to X-Large and five colors, and the merchant presents it as suitable to wear under clothing for all-day comfort. Note the straight hem finishes at the waist with a cropped look, so it may sit shorter than you expect.[1,2] | Supima® Cotton Smoothing Cami: Choose this if you want a soft, breathable layer for sheer blouses or a comfortable wire-free alternative worn as a light-support top — reviewers describe the thin, smooth Supima cotton as gentle on sensitive skin. It fits true to size with adjustable straps, though the length is hit-or-miss: newer batches seem cut shorter and may not cover the lower back or buttocks, leaving a gap with low-rise pants.[3,4] | Smoothing Stretch V-Neck Cami: Choose this if you want a fitted, sleeveless V-neck layering cami from Miiyu's Second Skin line, designed in Canada exclusively for Simons, with thin adjustable spaghetti straps and a soft, stretchy recycled nylon blend microfibre (80% reprocessed polyamide, 20% spandex). It is intended to create a flawless silhouette under clothing—a stated purpose rather than a reported result—and comes in Black, White, and Beige in sizes X-Small to X-Large.[5,6,7] |

Love it
Soft and comfy but as with all shirts from Simon's I find it a little short . . . . i wish they'd make T-shirts that would go a little lower on the hips
