I am really pleased with these..often "one size fits all" means one size fits all thin teenage girls but this comfortably fit my voluptuous self, and they are great summer leggings.  I am not very tall so they fit as regular length, which is fine-so many leggings are made for 5'7" or taller.
the only slight drawback, though it doesn't bother me because I wear them with a longer tee shirt is that they are quite sheer-you might think twice before wearing them to a co-ed gym with a tank top-great value!!
