I'm 52. I have pretty good legs (even if I do say so myself lol) due to a combination of running and walking and a lot of pilates so am happy to get them out in the summer. I usually aim for around the 5-6 inch length because that is long enough to easily cover my butt and not leave me spending my whole time pulling the middle down. That said, I've been wearing the same length shorts for about 5 years now.
The just above knee length that is currently in every store just reminds me way too much of 80s Minivan Mo(u)m with a bad perm. I'm 100% not doing that.
Just interested what kind of shorts you're all going for this summer?
