I nipped out to the post box today (work from home) and decided not to change out of my slumming it at home and working in the garden working from home clothes as I normally would to go out, as it is only 5 minutes away. However I suddenly felt self conscious about the fact that I was wearing shorts! Cut off denim shorts about 2/3 of the way up my thighs. (It has been scorching here today).
I hated feeling self-conscious but I feel like the skin around my thighs and above my knees has got less firm recently. (i'm 39). I do exercise regularly (running, swimming and weights) and the muscles are good, just not the saggy skin on top! 
How old are you and would you wear short shorts? I.e. not long "city" shorts, and not super skimpy up your bum ones, but 2/3 up the thigh type?
