Bridesmaids doesn't want to wear her size vent

I think this is a really difficult situation to be in because it leads to discussions about weight and that can be touchy for many people.
It sucks, but I think you should just leave it be. The wedding is still 4 months away- maybe she is on a weight loss program and is using the smaller size as motivation?
Worst case scenario and January rolls around- it still doesn't fit- she has to order a brand new one in a bigger size and pay for a whole new dress + rush fees/shipping.

Not your concern. She got a dress, she can figure out how to make it fit. Stop nagging her about it, I promise it's not helping anything.

One of my bridesmaids did the same thing. She bought a size that juuuuust fit in the store but swore she'd lose weight and it would fit perfectly by the wedding. She told me 3 weeks before that it's not quite zipping all the way but she'll figure it out. IDK what she did... but it worked out and the dress zipped for the wedding. So I know its hard not to... but don't worry, if my friend made the dress fit in 3 weeks then I'm sure your friend will figure it out in 4 months. I wouldn't say anything more to her about it, she's clearly self-conscious and encouraging a bigger size won't help. She can probably get the dress let out if need be but she probably won't want to tell everyone that's what she did.

Oh yeah, I totally agree with that. I'm just saying- since she's not going to do what's reasonable anyways then the worst case scenario is she has to pay extra money at the last minute. That'll be a lesson learned for her.

I have a friend like this. They are insistent that they are a 4 when they're more like a 12. I honestly think it's a psychological issue. Some people in the mirror think they're bigger than they are while others are convinced they're smaller. I'd ride it out and see how it goes as you get closer. If it doesn't zip by then maybe gently ask what her plan is or see if you can order another dress just in case? I understand that it's frustrating but I honestly think it's a personal issue and out of their control. My friend consistently wears skin tight clothing that does not fit and then brings up how she's a four. What? We weren't even talking about that. I love her dearly so I just go along with it. You might have to also

Like everyone else mentioned, bridesmaid/bridal dresses are generally a size or two larger than street size. I was a 6 for my friend's wedding and ordered an 8 dress that only needed hemming. What I would personally do/not do: I would let her know that her options consisted of either trying the size 8 you already have available, getting measured and reordering the proper size, or ensuring it fits for the big day. Should she need to attend the wedding in another dress because hers does not fit (and naked is not an option), she will be attending as a guest. The rest is up to her!

Wow that is super frustrating. The bridal store definitely should've made it clear to her that wasn't going to fit her. I also can understand her being somewhat frightened at the size number (as was i at first) but if its understood in the "bridal dress" world that the sizes run differently then she shouldn't be so insubordinate. plus who is going to know what size it is besides you anyway ?

I have a similar situation but can also see both sides of the story here. I have two bridesmaids who are just build a bit bigger and both claim that they are going to lose 75 by the time my wedding hits... that's 8 months away... Its just not possible to do in a healthy manner but they insist and refuse to go dress shopping until they are at their goal weight.. So im at a loss for what to do or say.

on the other hand, I understand where she may be coming from. As someone who suffers from anorexia and body dis-morphia it can be incredibly hard to except that you might not be the size you thought you should be. Bridal sizes can make matters much worse. I swore up and down that I was a size 2 because that's what i wear in jeans but when it came time to put me in a wedding gown they were putting size 4 and 6s on me and they were fitting just right and even snug at times. I was heart broken and so mad at myself because i thought that a size 6 was just too big of a number and i was so mad at my self for being so "fat".

I eventually just had to get over it and order the 6. Does it still bother me, yeah of course, but im working on it. Thats the thing about mental illness, it might seem ridiculous to everyone around you but to that person it is everything.. Im sorry I don't have any advice but just a little insight of what she might be battling internally. Id maybe sit down with her and just tell her she will be beautiful no matter what number is on her dress label but she does need to be able to breathe and be comfortable the day of and thats all that matters.

I agree with what some others have said... the number is really just a number, no one cares and no one will see it other than her. Everyone knows when it comes to formal dresses like that, the sizes are all crazy anyway. They're definitely at least 1 size too small, but usually closer to 2 sizes too small (just like wedding dresses). Maybe explain that to her and tell her you had the same experience with your wedding dress. I mean if she's stuck on the size and refuses to get a different size, that's on her. Just tell her you really want her to feel comfortable but regardless that's the dress and you're fine with her fitting into it however she needs to. If she wants to spend extra to get it taken out (if possible), that's on her. So frustrating for sure!

UGH this is frustrating. I am having a different issue with some of my bridesmaids as well. I hope it all works out for you.
