That's why I hesitated on saying anything, but it's not just a matter of being small all over. Even though my weight is on the smaller end, petite sized people (i.e. short people) come in all sizes... up to size 16 in most stores. What does a size 10 five foot tall person do? I can remember when I was in my twenties and looking for work clothes. It was really hard for me; I never wore pants and some of the junior clothes were not appropriate, even though they fit. I remember when Petite Sophisticate opened when I was in my early thirties. It was the eighties and I bought tons of suits there that I wore when I taught high school. I wore them on my interviews when I moved to MA. It was like I died and went to heaven.
And, I do think it's kind of discrimination when there's no clothing for smaller people. I can't help my height.
And I guess cycling clothes are just as variable in their proportions as regular clothes. I pretty much stick to 1-2 brands because I know they fit.
