I bought a vest top to try and it is wonderfully comfortable and secure (I was worried that it would ride up or something). It also doesn't flatten my boobs too much, I was worried about that too. But, by gum, it's a bit of a fight to get it on. The bra bit seems to roll itself into the t-shirt bit and it's really difficult to yank it down into position at the back. I don't have great shoulder mobility, so perhaps I should view it as a workout opportunity to increase flexibility.
