What size bravado tank top to buy?

[wem]

My chest size and cup size have varied hugely during previous breastfeeding and this pregnancy. I fed DD for 16 months and at one point went to get measured properly and bought 30Fs, by the end of breastfeeding this didn't really fit me as I had deflated a bit (), during this pregnancy my boobs have reinflated, and I've not been comfortable in anything other than 36 chest size. I'm guessing this is partly ribs being pushed out and partly weight gain. I lost weight fairly quickly last time, but can't guarantee that'll happen again.

Upshot is, I want to buy some bravado tanks but have no idea what size to buy as they use bra sizes rather than S/M/L.

I'm 36 weeks and I would like to get them sooner rather than later, but perhaps I'd be better off waiting and measuring properly?

Sorry, slightly dull question, but I would appreciate any thoughts :)

If it's anything to go by, I was a 34C pre-pregnancy, and am now wearing a 34E Bravado bra, which is a L / XL according to some brands...
The NCT do a free measuring service, and they stock Bravado too, if that helps.

Thanks for replying, realised after I posted that it was a pretty impossible one to answer!

Where would I go for the measuring service? Do they have shops?

Check 'em online - here. You basically pitch up at one of their rep's houses (or at least that's what happens in our area), all very discrete and professional.
