I just ordered my first KWIK set, and I am blown away. I am in love with the plum colour, it is even prettier in person. The fit is amazing, and they feel like a second skin. I used their sizing chart to order because I was getting it shipped and decided to go with a size M after seeing it was similar to a lululemon size 6 (loved that they had the popular brands comparison on their chart). Love the whole set!
