I tried several different styles and manufacturers of non underwire bras and this one is the hands down winner. I wanted a comfortable everyday bra that I would forget I was wearing and that I would not feel like readjusting constantly. I have a small rib cage, but being older my breasts are perhaps a bit lower than they used to be so even though I only weigh 112 lbsI had to go to a Large in order to get long enough straps. I adjust the band on the tightest notch. I did not choose this bra for active wear. It does provide some lift, but if you are looking for a sports bra this is not it. This bra does provide some separation. It does not squish your breasts together. It provides a nice natural look and because the cups are lined there is no nipple show through. I have ordered a few of these now and have found that sometimes they arrive with wrinkles in the cup material. At first I sent those back, but now I get the wrinkles wet and gingerly use a warm iron to smooth them away. I am pleased with this bra in size Large. It works for me. I am a 34DD. It provides some support while being so comfortable I am happy wearing it all day. I like the full coverage. I can lean way over and not worry about slipping out of the cups. I have worn it stretching during floor exercise and it does not ride up.
