When I was preg I had to get fitted & bra's ordered in from Myer, as I went from a 12C to a 12GG!!!!
Which they literally do not stock, they were ordered in & about $70 ea, but wel & truly worth it, as I still had 6 weeks to go of my preg & then my milk coming in & I was a bad milker & only fed for 6 days, too much bleeding & pain...
I probably only wore the 2 bra's I bought for like 9 weeks in total but still was worth the money!!!!!

Even though I was about 5+ weeks with my recent preg, I had gone up from a 12C to a DD cup & they were still souffleing over the top of the bra!!!! My jugs just get massive...
I am a size 10-12 in clothes (at the moment a decent 12) & my breasts just looked ridiculous last week, as they were hard canteloupe's!!!!

Go the good bra!!!!!!
