Do I need to wear a bra in school?

I haven't started HRT yet but I'm starting it quite soon and this might sound like a strange question but I was just wondering, considering I'll be getting changed with a bunch of other people while also getting boobs, should I wear a bra or is it not really that important? (basically my dilemma is that if I wear a bra, I'm likely to get strange looks and be judged, but if I don't wear a bra, it might be weird considering I'll be growing natural boobs)
