So I've found the past month or so I've not been able to wear my binder as much as I'd like, which has lead to a lot of distress about my chest. My current solution is some loose, heavy sweatshirts that hide my chest well as the heavier material doesn't cling at all. But I'm becoming more and more aware that the weather here is slowly getting warmer, and it'll reach a point where if I wear these sweatshirts I'll be overheating. So I was wondering if anyone has any advice on what I can wear that may lessen my chest dysphoria but is also not too ridiculously hot once Spring/Summer come along properly. I don't mind being a bit too warm, but the sweaters will be too much. I'm not sure if it helps, but I'm non binary so I'm happy to consider items from both the mens and womens clothing sections.
I can only speak from my experience trying to keep my developing breasts from being detected while I was on HRT prior to transition. In warmer months I would wear a slightly tight black tee shirt (the black helps hide the shadows!) and then a baggy loosely buttoned short sleeved shirt (usually with a checked rather than striped pattern) over the top. It did the trick but then I only had B cups, don't know how well it would work with larger breasts.
This works well and is very light weight. I was just using it in mid 80 degree weather and didn't feel too hot.

It can also be folded over itself for more compression.
