Plus size bridesmaid advice

We have a small wedding party with only 2 girls on my side so I'm going to buy thiet dresses for them. I want them to feel comfortable in whatever dress we decide on but they haven't been much help narrowing down the choices. I'm going with azazie as they have a large selection of knee and tea length dresses in the light blue color I wanted so I made a showroom and added a bunch of dresses for them to look through. Most of the comments they left were just versions of " I'll wear whatever you want" and we only eliminated a small number of choices. I asked if they woyld prefer to wear something not a dress like a suit or something but they both want to wear dresses. After talking to them a bit separatly it seems like thier biggest concern is what the dresses would look like a plus size girl as they both are. Some of the azazie reviews have pictures of the dresses on real people and those are helpful but some of the options we are looking at don't have any customer photos. There are too many dresses for me to have them try them all at home. Have any plus size girls worn an azazie dress and how were they on you? What are your favorites? One is about an 16 and one is about a 22. Thank you!
