I bought a Rockets pair and Celtics pair. I bought them in a M and they're definitely fitted shorts. If you want them looser than I would recommend going up a size.
Bought a pair of the Dame 4's last week and I do love them. I might buy the white pair with gum sole next week and I'll definitely be buying the black pair when they release.
Tried the Pioneer colorway on in the store and just wasn't feeling that colorway. Hopefully the GM colorway end's up in more stores sometime in the future.
