Great for thick thighs!

shorter products always roll up my thighs. These are perfect! They produce a smooth look and keep my legs from chafing so I can comfortably wear dresses and skirts without also wearing pantyhose. I love them so much I bought a second pair!

Love my shortlettes!

I'm so grateful to Undersummers for your tolerance of my returns of my very first order. Now that I've made sure of my size, I'm happily wearing these well made garments. They are comfortable under pants as well as skirts. What a wonderful product! Thank you, Undersummers.
