I have worn underwire bras in the past and have liked them, but hadn't done so in several years. Working from home and sitting for many hours my posture has suffered for the worst. I decided to try longline for more support and I am very happy with this bra. It stayed put, held in my tatas, and the straps were not an issue throughout the day. I forgot it was on. My shoulders were relaxed and my ribcage was supported and upright. I had lost weight and I have bought and worn a 36 for years. I measured and my size calculated to a 34. I was reluctant as I have usually been a 35 in the past and a 34 was always too small. The bra fit exactly and snug. I couldn't decide if it was too small, just right or if I should order a 36. I wore it all day today running around and it was so comfortable. The elastic mesh around your ribs is not thin and holds it shape. Wires are well intact and did not cut in or sick me. Straps are thin but did not cut into my shoulder. They did not fall down. The height of the sides you see in the pic is the same for the center back. There are 3 rows of 6 eyelets in the center back for adjusting to your size. I was hooked on the first row which would give you the largest width. This was a very solid bra, comfortable and well made. I washed it before wearing it in a lingerie bag on gentle cycle, air dry. No issues there. I'm ordering 2 more at 34B.
