This literally is an amazingly flattering top for being such a simple black tee. The super deep and wide v-neck is the secret, along with the slightly diagonal silver thread lines on one side which add a little surprise and interest. The fabric is extremely fine, soft, and lightweight but, since it's black, you can wear it without a bra if you want. I do. The fit is nice and clingy in small for me, and I can wear an xs in the singlet tops.
