My personal favorite is T8615. It looks similar to the dress that i tried on, but I can't pull it off.

I have 3 dresses. The first one i bought wasn't really me, so I went and found a different one, one that I fell in love with. but unfortunately, I did like you, bought it because it was on sale and I didn't want it to be gone if I changed my mind and wanted it. but now looking at it, it's all stained and it's ivory (and i want a white dress) so i ended up borrowing a friends dress whose wedding i served in. it fits me like a glove and makes me feel like a princess and I didn't even have to pay for it!

I love the original dress that you chose, but if you're not 100% satisfied with it, you may want to get something that you are going to love yourself in.
