Women's Seamless Slip Short

I wish No Nonsense made a mid-thigh version of these! Like many women, my thighs touch and rub when I wear dresses and skirts. In the past, I use to wear yoga/bike shorts to prevent this. I'm on a quest to find the perfect slip shorts though because they can be lighter and cooler to wear, as well as no seams. Now that I look at the picture on the package, the shorts on the model aren't very long either. So bummed that I had to return these.

The waist sits low, causing unattractive bulging. The legs are too short, and ride up, causing -- chafing!
