All mine are suitable for the 20 something me so I've chucked them. I'm 36, have a serious job, not great legs, scarring on knees and hate shaving my very white legs. I'm on maternity leave so I don't have to be professional looking, but would be mortified if I bumped into someone from work with my bum hanging out.
What shorts do grown ups wear? I have a fine collection of both smart and casual shorts for a 3 year old boy
