Bra Friendly?: Totally Sheer- Your Call on Undergarments!
From L'Agence:
The Amarenthe is a dark and delicate new layering option. Made of corded lace, this long-sleeved blouse has lightly puffed shoulders and scalloped hems for added femininity, while the mockneck and button-detailed cuffs remain purely classic. Style it layered over a black tank or sleeveless dress.
