If she’s 5’4” and on the heavier side, we’re up in the 36-38 back territory, possibly 40, and unquestionably beyond normal cup sizes. So, something like 38L/LL.
So custom bras? I'm curious how much these cost, and how do you go about getting one.
My first job after school was working in a small fashion retailer making one-off garments, so I ask the question with some knowledge of making patterns for people.
I have Abbi Secraa @ 36LL and Nadine Jansen @ 38LL - when we get to very large sizes like that, I guess the difference isn't that much?
When things get to a certain size, you have limited options.
You can wear bras that are as close a fit as you can get, which isn’t ideal.
You can not wear a bra at all, which is a terrible idea.
Or, you can pay for a custom bra - and they are not cheap. I’d expect anything from £150>, and even then it might not do the job too well.
