I am kind of thinking of experimenting with this kind of thing. I have always had some dysphoria around my breasts, as was thinking of trying this.
OTOH, I hate bras. I hate sports bras (perhaps a bit more as they tend to be more pinchy). So anyone ever try some other things. One thing I do is just do the loose t-shirt (large or extra on a 5 foot one person, appropriate weight person). Or perhaps if the weather works for this t-shirt and polar fleece.
Now we are heading into summer and no P. fleece. I read that someone used Under Armour heat wear.
In my mind I don't necessarily want to completely flatten but could be much noticeable. Between a B-C cup btw.
