These bras are very comfortable and have great support without underwires. They are lightly padded so if it's really cold I'm still a little nippy through the fabric. I normally wear a 42D and bought these in 3XXX which fits well. I was concerned because the straps are not adjustable but so far they are fine. My hope is that over time they don't stretch out but it's only been a month or so so far. The worst thing about these bras, and I own 4 of them, is the color description on some is not at all accurate. Light pink is really dark pink/ peachy and dark pink is a pretty horrible red. Green is a dark forest green. Lavender is good as is beige.
