Hey there everyone! ok my dress is a strapless a-line. And I have no idea what style of dresses my Maid of Honor and Brides Maids should wear..

My mother has suggested they pick their own out, but there are two of them I dont think I can trust to get ones that would look good.. So if I could tell them, Ok here this the styles you can choose from, have at it.. Id feel better about them picking out their own.. Let me know..
This is my dress
