Soft Periwinkle Columbia Leggings - Med (unworn, no tags)

These women's size medium leggings were a gift but they don't fit me. They're unworn except for trying them on. It seems like I have also removed the inside front tags that would have showed what the material was, how to wash, etc. Here's the info I have: -Stretchy and extra soft women's periwinkle performance leggings -Material is medium thick (feels like nylon/polyester but I don't know, sorry!) -Size Medium -Front inside key pocket -Length: ~38 inches -Waist: ~31 inches
