Gorgeous dress! I wore it once to dinner with my daughter. It's just like new!! I love it but won't wear it again - I don't get dressed up often and when I do, I like a new dress. I had to have it and it gave me Taylor Swift vibes when I saw it. It's a M and fits true to size. I wore a bra with it although the description says to wear strapless or petals. A bra worked just fine. Info from Lulus: Bust: Great for any cup size. Waist: Fitted - very fitted at natural waist. Hip: Loosely Fitted.
