Where did you buy your baby shower dresses from?

I won’t have any family with me for my baby shower since my husband and I live in another country. So, I want to dress up, look good and feel good! My theme is along the lines of “baby in bloom” with a lot of floral decor and a cake decorated with tiny little colorful flowers. But, I don’t necessarily want a floral dress - something with tulle would be lovely!
