I'm 5 foot 2, small size 8, and would like some better quality leggings than the ones I'm currently wearing that have gone baggy. Are Boden teenage leggings suitable for a small adult? if so, what size? or do you think they are overpriced tat and I could do better elsewhere, in which case, where? Also I don't want black leggings - navy, grey, brown, whatever, but not black atm. Thank you!
