These fit true to size & are very stretchy! (if concerned, please see size chart) Like most comfortable pants, these do 'give' slightly after the first couple of washes, so if they are slightly tight at the beginning, do not worry! It is better to have them tighter rather than looser.
These leggings have been extensively tested for months, being used daily for riding & being washed everyday, and they still look new.
Kiv is 5'9, usually wears an AU/UK size 6 and is wearing an XXS
Unfortunately no washing these in over 30 degrees Celsius
