Help me bra people! How to fix this

[twolittleboysonetiredmum]

I’ve always been pretty good about regular bra fittings using bravissimo etc and have also used the method linked to often on here (can’t remember It’s name but involved measuring under boobs and widest bit of boob and doing a calculation)
So I’m fairly sure my bras fit ok. However, recently I’ve noticed I have underarm fat hanging over when I wear vest tops and I can tuck it back in my bra but it works it’s way out again! It’s awful! I am nearly 40, is that why? I’m not overweight. Help!!

Anyone? Save me from my creeping armpit fat!!

Join boob or bust on fb...if you post a picture they will do a fit check and give fab advice

Following with interest, I’m in my mid 20s and size 8/10 with fairly small boobs so I’m not sure why it’s happening! I get the same in a bikini

I had this. In my case going down a back size and up a cup size silved it. Y bra was actually slipping down and then my honking it back up was causing the problem. And not enough room in the cup so some breast tissue was spilling out.

I'm a size 8 by the way, so nothing to do with weight, and in 50s so not age related. It's a size issue

Have you done your boob or bust measurement?

Thanks for replies - I did a measurement a few months ago and think I’m in the right size. Interesting about going up in cup and down in back - I’m in a 30 back currently tho so that’s pretty limiting. Can’t hurt to try. Is boob or bust a private group? Slightly unsure about posting a photo of me in a bra on social media but would like some advice!

@twolittleboysonetiredmum yes it is a private group, lots of people share pics mainly headless so no need to be embarrassed
