Help! Need a cute maternity dress.

V&G101808

My graduation is in less than 2 months and I'd love a cute dress to celebrate the occasion.

I've seen a ton of cute stuff online but I'm hesitant to order it with the hassle of shipping and having to return it/exchange it and wait for a new size.  I'd much rather try to find something in store that I can try on.

Any suggestions? I didn't see a very big selection when I went to Motherhood a few weeks ago.  Any department stores carry a nice selection?

FWIW: I'm short (5'2) and like to keep my dresses around the knee.  I don't think a maxi dress would be very appropriate for this type of occassion...
