These leggings are great.  I bought almost every color.

The quality is great, material is soft and some type of lycra so it does have a sheen to it (not the 80's shiny spandex type).

There is an odor to them, but I washed them by themselves the first time and the smell was slightly there but not enough for me to wash them again.  I wore them and started washing them with my other clothes.

These leggings SEEM to be truly one size fits all.  I am 5'2" and my niece is 5'8" and we both fit them.  I can wear them during pregnancy and post pregnancy.

Overall, a great buy for the quality and price.  i have been buying them for family as well.
