Thank you for joining MyNudies. Sizing, stretching, and shrinking are common topics. There are a lot of variables to consider....style, type of denim, how you wear them, etc. I know several members who like to get their denim tight and then have them stretch. Personally, mine don't seem to stretch that much and considering I live in a hot place I don't wait 6 months until washing. Grim Tim is an excellent choice but you might want to check with other members too about their stretching experience. Checkout the Grim Tim section of this forum.
