Both are the same size 2. I bought the purple one last year, and the blue one was newly ordered from WMTM. I thought I got a steal! But they seem to run bigger than all older align I have. The waist and hips circumference are about 2cm wider, and the rise is higher by about 1cm

Is there recent change in sizing, or I am just unlucky to get sample items in store that has stretched out maybe?
