In warm weather (here that means HOT 4-5 months/year) I wear sturdy shorts and a sleeveless t-shirt, with maybe a longsleeve white cotton shirt covering in the afternoon sun (but I try not to work in the afternoon sun...). And a big brim hat. In the winter I wear old jeans, or on cold days my insulated bib coveralls, a thermal shirt, insulated vest with a barn coat over. I can remove the barn coat when I'm warmed up and the insulated vest keeps me warm, while allowing for unrestricted arm movements. The one thing I wear in any weather is my very sturdy slip-on-and-off work boots with thick cotton socks. The protection they offer from twisted ankles, foot injuries and FIRE ANTS are worth the slight heat factor in summer (tho it's really not that bad). And they look so fetching with shorts!

If I wore nothing else at all, I would still be stomping around the gardens and fields with those babies on....
