I am a ftm and breastfeeding my little guy. I'm doing the one up one down method. So wearing a cheap vest and a loose top to pull up. I've tried this with non stretch tops and its not as good so would like to pick up a few nice t shirts. I'm planning on loosing weight as im prob about a size 16 now with big boobs so don't want to spend loads but also like loose clothes so would like to still wear them as oversized in the future. Any suggestions?
