I ordered a size up per the advice from others, but found the smaller size still a little roomy. I had to wear some double-sided tape to keep things up, but thankfully never had any unfortunate wardrobe malfunctions. Being on the tall side, I loved that I could wear heels with this dress without making it an awkward length on me (it's long!). It was incredibly comfortable for a summer wedding, and I received tons of compliments on it. I felt beautiful in this dress--a wonderful perk for a mom with a small baby at home--and my husband loved it as well! The only negative is that the dress had some damage to it. It wasn't noticeable, but the overlay around the base of the zipper had come undone. This dress is popular and is likely rented a lot (with good reason!), but I wish they had inspected it more closely before sending it out to me.
