When to get measured for a bra if still breastfeeding?

[KBwan]

I'm still feeding my (fourth and final!) baby, who is 16 months. I've promised myself for about the last 8 yrs that when I've finished being pregnant / feeding I'll treat myself to some lovely new bras. God I've earned them.
Anyway, baby is down to 3 feeds a day and my breasts are always pretty soft... When he stops will there still be some mass deflation to come, or can I go ahead and invest in something that a) fits and b) doesn't have to have easy access?
Bras are so expensive I'd rather not have to re-invest when he does stop completely.

Unfortunately cannot advise as DS2 is 3 and still having one or two feeds a day (never intended to feed for this long and he just didn't stop...). I will say my size hasn't changed at all since he was 18 months or so (apart from when I lost weight due to illness) and he doesn't feed during the day, so I just went ahead and bought some nice non-accessible bras. Hoping there aren't any dramatic changes when he actually stops entirely...

Recommend Brastop or one of the outlet lingerie stores like Belle Lingerie once you know your size as you can get last season's stock from "proper" bra brands at v reasonable prices - at least then you won't feel like you've made too huge an investment!

DS mostly* weaned a couple of months ago at nearly-four. My breasts seem much the same size and shape as they have been since he was about 18 months, which is when he was down to about 3 feeds a day.

• has fed maybe five times since, less than fortnightly.

I'd buy at least one good new bra in your circumstances - unless I was planning to wean completely within the next 3 months or so.
