Buying Dresses Online?

I bought mine off ebay, by seller halfoffbridal. I found the dress (it was a sample) I had my heart set on, in my size, brand new for 1200 less than buying it in the store. They have a return policy, although it's not the greatest.

I tried it on and it fit perfectly and luckily I don't need any alterations. Although one thing I did not consider after buying it was the length. I am very tall as it is and if I needed to make it longer, I wouldn't be able to.
