I haven't worn tights much in the past before as they always seem to run small & I haven't worn a lot of skirts. However, I'm thinking of doing a couple skirts this fall with my Cole Haan boots & I thought some tights would be fun peeking out. I'm looking at 2 in the NAS catalog http://catalogs.shoplocal.com/.....arid=15193 (page 11, the diamond pattern &/or charcoal). I'm wondering if they are worth the price? Also, do you usually size up in them or are they pretty true to size?
