A great top! I had already cut off the tags before I realized it was slightly too big for me, but it’s only been tried on and never worn out. Size is Medium. The built in bra is comfortable and eliminates the issue of having to find a matching bra. From the official description in Uniqlo’s website: - Sleek tank-top design. - Opaque, narrow-ribbed fabric. - The shoulder shape creates an airy, effortless look. - Built-in bra cups mean you don’t need to worry about your bra straps showing. - Navel-length cut. - Perfect for layering or wearing on its own. - Pairs with high-waisted bottoms to show off some skin for an active, healthy style.
