I just saw this, sorry. Anyway, I haven't tried this top on but I saw a girl in the airport with it on past weekend. It looked really cute IRL and I liked it so much I'm going to to mall either today or tomorrow to try it on. I'll let you know how it fits.
I actually went to AE today and bought it! The store had both a 0 and a 4 in stock, and to be honest, because of the smocking in the back, there wasn't a big difference in size. I ended up getting the 4, only because it was a little more comfortable, but looks-wise, not much difference at all.
It is very cute IRL-- stores seem to be running really low on sizes, so go quick! Thanks for the reply!
I'm glad you found it. I ended up ordering it online because all my store had was a 12. I ordered the 4 and the 6 because with an order over $50 it was free shipping. So, I saved the shipping charge and I'll be able to decide which size I like better. The top really is so cute IRL.
