I have DS 15 and 19, these are the brands they wear/ask for;
Carhartt, Dickies, Adidas, Nike, Fila, Palace, Champion, Magenta, We Are Brain Dead, All Timers, Ralph Lauren, Tommy Hilfiger, North Face, Kappa, Vans, Reebok, Napapijri, Off White, Stussy, Supreme, Polar SkateCo and Thrasher.
They get a lot of stuff from Depop which is secondhand, so way more affordable and better for the environment. I like the fact that some of the brands are also really hardwearing and useful - like fleeces and waterproofs
but they don't want brand new, it's all about the 'vintage' 90s!
