I seem to be in between sizes in the Piper. A 24 in TS is a perfect fit for me while a 24 in the Pipers is tighter in my legs than I’d like, but a bit big in the waist. (For the record, my legs have always been thin and I struggle with jeans because they’re often too big in the thigh).
The 26 is better in the legs, although maybe a tad big, but then large in the waist. Very frustrating, and I’m glad to read that I’m not the only one that they slide down on. I’m not stick straight and not curvy, so I’m not sure if there really is a body type that they fit perfectly. They’re all so cute that I want them to work for me!
