Beautiful summer tune dress from American Eagle

I am a solid size 4 and this is labeled a 12 but it was the last they had. I decided to try it on and it fit! I LOVE this dress for the summer and received so many compliments. I just haven't given it the love it needs lately. Stretchy bandeau style top with a panel of extra stretch in the back. This will easily fit a range of sizes so I will label as a medium.
