Bare legs?

Hmmm... 3 days of (false) summer this week led me to change my work attire for my legs & feet. I wear tights in the cold months, and bare legs in the warm months. Last fall my bare legs and sport sandals (Chaco Z1s, what else!) lasted until late October when I headed off to Hawaii for a week and then returned to noticeably colder weather. This season? After 3 days of summer-like weather, comfortably heading to work wearing my normal skirt - but with bare legs - I don't think I can go back to wearing tights. I wonder how long this will last...
