I've never measured, but I think our shoulders tend to look less balanced because we lack hips (usually). I always had fairly strong shoulders, though phsycially I was never that big (172cms, 70 killos) With hormones I have lost some on my upper body so far and some weight (now about 65 kilos), and have a bit of a visible curve to my waist and that has made a lot of difference. I seem to be toned as ever which I think is hot. Still early days.
You can disguise wide shoulders to a certain extent - like wearing tops or dresses with spagetti strap, fitted tops that flair out a little near the bottom, and wearing short skirts with a bit of volume that fit snug at the waist can help.
