Hot Milk makes some really gorgeous maternity bras that are all lacy and girlie but give you all the right support you need, check out their site and see if you have any local stockists

I've found that maternity bras are well worth the investment no matter what stage of pregnancy you're at, because instead of 3 hook-and-eye closures, they have nine or ten, allowing for much more expansion of your breasts, and then you can tighten them up again when your supply settles and your boobs go back to normal a bit. Good luck finding the right ones for you, can't hurt to go shopping now and see what's on offer HTH
totally agree with this (as i sit in my sexy red lace hot milk bra lol! i got mine fitted this time at around 12 weeks cause i just couldnt stand the underwire. the good thing with the Hot Milk ones i have found is that they have a generous stretch in the cup and like Glam mentioned they have heaps of hooks to allow for the expansion as your ribs decide to go east-west.

if you do feel a bit iffy about buying/spending the $$ on a bra like Hot Milk in case it stops fitting (although if you go to a proper bra store they should be able to fit you accurately for the maternity growth ITMS) then i would go a couple of cheaper ones...also a great idea for ease and numbers of bras when you start BF. i've had pretty good comfort from simple ones like lovable...(i did this last time as well when my milk came in as they can get REALLY big for a couple of weeks there before they settle back down...).

HTH!!

also check out 'cake'...they seem really nice and girly too, but havent tried them...
