help me find a bridesmaid dress

I've asked my girls to choose an blue dress, short/knee length dress for my August wedding. I also asked them to avoid lace if possible, because my dress is lace. So far, four girls have a dress, but one is still struggling. Can you help us find options for her to look at? I feel like we've looked everywhere!

She is a size 16 and very busty, and she never feels comfortable in strapless or anything too revealing. We're trying to stay between $100-150, maybe up to $175. If it makes a difference, my wedding is being held in a church at 4:30pm. I feel like it has a fairly laid back feel, nothing super formal. The guys will be wearing gray suits.

Here are the other girls dresses:

Thanks for your help!

They say bustier girls usually look good in V-necklines
