The new Waltz pants have ties in the bottom to turned them into crops. However, it looks like she knotted the fabric on her left leg. Hmm, need to see more photos for clarification. Update- readers are writing in there is no tie at the bottom and that the educator invented this style. I know the old Jesus pant did not have ties, so was puzzled at this update. However, lulu is a bit tie-happy on their pants IMO so it could have been possible.
More photos showing the Willpower catching in the armpit area causing creases on your chest (and now back!).
