They will both have a different feel to them, but they're great.
The top dress is a thicker satin and may have boning in the dress, but they are super shiny and satiny and feel great. I prefer these Jessica McClintock dresses to the one below it, but they're both fun. That Morgan Co dress may be a trap. Ruby Rox is okay...I think I have a dress or two from them, but sometimes their dresses can be traps too. They have a lot of dresses that look like satin and it's similar, but it's super thin.
