Thanks, everyone, for helping me analyze and giving me some feedback and ideas. I realized something yesterday when I took the puppy out for a run -- my running shorts are not long, maybe a 5" inseam?, but I actually think they're more flattering than many other shorts are on me. Perhaps it's the curved hem. I wonder if it would be worth looking at some similar styles, but not quite as gear-ish. I found the Asos shorts below and wondered if in the Tall version they might work for me. I like the print very much. They don't list an inseam length.
Rabbit, it's so funny -- I have a harder time with skirts than with shorts, even. Skirts just seem to emphasize the expanse of my hips. At least pants and shorts visually divide the area, if you know what I mean.
Isis, I like those Asos basketball shorts -- I just wish the color palette was more in line with what I have in my closet. The flower ones are really cool, but I don't think that pattern placement would be too flattering on me.
Carla, I'll check out LE, thanks! I may also have to try the Gap ones Angie recommended.
Again, many thanks, all!
