I have a lot of these "squishy" tops. I hate wearing bras, I'm not really large, 5'5" and aout 135 lbs with a c cup.
So I like something that holds by chest still, but don't like underwrites or "shelf" styles. So this one works ok, doesn't roll up, tucks in fine, but a little flattening, more than the Barely There ones or Flexsees that I like a lot at the moment. Very good fit though, not strangling or crushing, I feel comfortable all day and still held together well.
