American Armhole Tank Top with Built-in Bra, crafted from an original blend of Supima, a fine extra-long staple cotton, and luxury silk.
Cotton's airy cushion, combined with silk's hydrating smoothness and subtle shine, helps to create a relaxing, stress free fit. The rib fabric's ability to stretch and return to form ensures a comfortable, snug fit.
Featuring a moderately high, close-fitting neckline and wide American armholes, this tank top provides a stylish and comfortable frame for the shoulders. The design allows for a flattering reveal of skin, making it versatile for wear alone, under a shirt, or as an inner layer for open-knit sweaters.
- Cup is removable. Wear with a bra of choice, depending on preference.
- Soft-fitting elastic band goes full circle under the bust, giving you gentle support.
Khaki Gray, a mix of nuanced gray and smoky green. Creates a more sophisticated impression than casual khakis.
