To start I'm definitely don't think my friends should plan thier lives around my wedding. Also I have a maid of honor amd a bridal matron but for simplicity in going to call them both bridesmaid. Since I only have two maids I went ahead and covered the cost of thier dresses myself and yhe dresses have already been ordered an delivered. Over a month a ago when the dresses arrived and we were doing a fit check with the friend in question I brought up the return window for the dresses. She said she was working on losing a little weight before the wedding and she was telling me about how she didn't want anymore kids after how rough her last pregnancy was on her body. Then a couple days ago, tye day after her son's second birthday, she texts me that she decided they do want to have another baby amd they are going to start trying right now. I tried to be supportive while also also reminding her that the return deadline for the dresses had just passed and the dress is cut to her current measurements. She keeps going on about how it'll probably not take right away but if it does she could be anywhere from a couple weeks to 4 months pregnant by my wedding. I know every pregnancy is different but with her son she gained 15lbs in the first trimester in part due to thyroid issues. I told her that if it goes that way again and her current dress isn't able to be altered to be large enough she will need to pay for a second dress herself. Now my problem is that the dress style they currently have is no longer made and has a high-low skirt that doesn't have a match in the current dress line up. I payed for my girls' dresses specifically so they could match exact since I only have two and mismatched but same color dresses don't look the same on two people vs six. So if she needs another dress, could I have her pay for both her's and the other maid's since she knew she was asking after the return date cutoff and I already payed for two dresses that can't be used? Again this is only if her current dress can't be worked with. Thoughts? I really can't afford two more dresses. Thank you!
