I ordered 3 boxers size small for my first order. Everything went well and everything fit perfect. Ordered a second time size small, one pair on the 3 ordered was too small even if it was the same writen small. Wrote to Knotty and got a discount for a next order. Ordered a tird time (could not add the discount code because of the sale that was going on), and ALL the small size are too small. Don't know if you change your sizes in the month and a half period, but I am not happy because I love the first pairs that fits me. They are confortable, but why when ordering small sizes some fits and others are too small???? There is about an inch less on the elastic on the pairs that are too small compared to the pairs received with my first order that fits me.
