Husband trying to help my wife find a bra that finally fits : looking for brand recommendations

Hi everyone,

My wife has been really frustrated trying to find bras that fit comfortably, so I’ve been trying to help however I can. The main issue is that there’s always gaping in the cups.

After seeing this subreddit recommended a lot, I used the calculator with her measurements, and the suggested size was pretty different from what she’s been wearing.

The calculator suggested 28B/C and 75C in French size :
1 : 69cm
2 : 68cm
3 : 67cm
4 : 74,5cm
5 : 77cm
6 : 76cm

I’m not trying to shop for her just help point her in the right direction because she’s pretty discouraged at this point.

Any recommendations for brands or specific models would be hugely appreciated. Thanks!
