Like many others, we have had to postpone our wedding. Since then, one of my bridesmaids has been trying to pressure me into letting her change dresses. She went with my mom, other bridesmaids, and I to pick out bridesmaids dresses at David's Bridal. Originally, everyone was going to wear a different dress, but several of the girls decided they liked the same dress so we all agreed on the same dress including her. She's since lost some weight, but not a ton. I would guess about 10 pounds. She has had the dress altered and she now thinks a different dress would be better. I'm not for this idea because she would now be the only one in a different dress. She isn't maid of honor so I think it would look odd for her to be in a completely different style. She's messaged me a couple of different styles she likes, but I haven't really said anything. Is it wrong of me to tell her no about switching dresses?
