Bridesmaid and moh dresses

I agree with pp. I'm not a fan of asymmetrical hems, so I'd definitely choose the even-hemmed style. If you want MOH to stand out she could wear a complementary color or you could add some embellishment to the sash for her dress. That will be more subtle than a different color dress, but it will be noticeable. (Also, people will know she's the MOH because she'll walk just before you, stand next to you, hold your bouquet, etc., so she only needs to be dressed differently if you want her to be.) PS -- pretty dresses!

I prefer the even-hemmed dresses. A different color dress for your MOH is totally fine!

These are so gorgeous!!! I would pick a color and have them choose otherwise, but that's just my preference
