Breastfeeding past 1 year - will my bra size change?

[weasle]

Just before I splash out on much needed new bras, wondered if I will stay this size for long?

Ds2 is 1yr in 2 weeks and I would like to keep feeding him as long as possible. Although, it is a real struggle to get him to feed in the day at all now, so not sure if he is weaning . Still has a night feed or two though!

TIA

My norks got to their end size when DS was about 16 months - before that he'd been having daytime feeds as well as first thing/last thing and night.
