How can I make my bridesmaid change her dress without hurting her feelings?

Double sided tape. Sounds silly, works amazingly well. I am petite but have larger breasts for my shape. I stupidly bought a strapless dress, which was fine, while I was standing still. Even with a bra, it was slipping. So, I bought and used double sided tape and it kept me secure in my dress, all night. I believe it is even made for garments, so it does not harm the fabric. Don't single her out, just buy it and take it to the room where everyone is getting ready and say that you would like everyone to use it, so there are no "accidents" during the ceremony/reception. Use it yourself if you have to, to keep from hurting anyone's feelings or embarrassing them. Good luck and congrats on the wedding!

its your wedding and your day. u need to be honest with her, and tell her how u feel the only other thing i can think of is having them all wear little jacket coverups. u dont want the groom and his groosmen to be distracted itll ruin everything

Simple...you purchase three matching shawls or shrugs for the girls to wear...say you love the look and want it for your wedding photos... ...and if she flashes the guests at the reception...her bad.

Can you talk to her about it? Just say that it'd look better with a bra? Or talk to the other two about the straps?

Explain to her that if she would to have a wardrobe malfunction during your wedding it would be very embarrassing for both you and your friend.

I would sit down and talk to her it is your wedding day just tell her honestly that you don't think that she will be comfortable and that you have seen before situations where people fall out of their dresses "its happened to me and I wore a bra actually" while dancing at the reception and you would feel a lot more comfortable with her wearing straps or a bra or whatever it is you are looking for her to change if you say it nicely I think you will get what you want out of the conversation. Don't come at her like your attacking her or your bridezilla but heck you were nice enough to let people pick their dresses as it is.

I think you should go to the other girls and plead with them to add straps. Its the most sensible solution, and its also the most sensititive to the girl with a large chest who cant control the way the dress fits her. The straps dont need to be a permanent part of the dress. They can have straps added that literally hook inside the dress. Once the wedding is over, they can unhook the straps if they wish to wear the dress again.

A friend had a similar problem, except her bridesmaid was plus size all over, and her dress was so tight that she was pulling it up and down all evening, her zipper would not close, it was unzipping itself all eve, and the weight of her no bra breasts were pulling down the dress from the top, and her hips were pulling it up. And there were bigger sizes available! My suggestion is to take her to a store that the salespeople will measure and fit her into a bra appropriate for the dress. Take the dress with you, with the sales tag. And not the size bra that she thinks she is, the one she actually needs. Is she still of a size that the average department store carries it? If not, get a Lane Bryant catalog and order something, they carry good underwear. Sometimes, being a friend means saying potentially hurtful things. But when they are said with love, and in the interests of making that friend feel beautiful, it is worth it. And when you take her and talk to her, make it all about her. Don't be a bridezilla, be a friend. Have her watch that show "Say yes to the dress" or the one with the two hosts that take the person in need of a style change to New York. She can see some of those women who are truly a ugly mess, who have no hope of ever looking good, and they make them look like princesses, with just some clothes that fit that minimize figure flaws, the right underwear, and a little makeup and a flattering hairstyle. Warning, there might be a problem, putting a bra or bustier/corset under a dress that is already cut to fit might not work, it might not go under there.

Yikes, this is a mess! If getting all 3 girls to wear straps would solve the problem, I'd suggest that, but when the puppies are too big, straps don't change that. They might even make it worse. The only thing I can think of is get a specific solution from the seamstress as to what will fix the other girl's dress, and then tell the girl this is how the dress will be. Yes, it risks hurting her feelings, but she's pushing the envelope here with her choices, so you're being forced into it. Then, I'd beg/plead or do what it takes to get ONE of the other girls to wear straps. That way, all 3 dresses will be similar, but not identical, and she won't stand out in any way.
