Im 15 year old boy and love clothes but i have a small bedroom and i cant fit a wardrobe in my room i have chester draw but found my clothes get jumbled up and creased in their which stresses me out i have now got a pole (curtain type pole) from 1 side room to other to hang my clothes it seems better but i have bought fred perry clic jumper and t shirt costing 115 pound fenchurch and superdry jackets but heard it was no good hanging jumpers or knitwear so how do i keep my clothes ok without having to worry about creasing pet hairs and them being ruined
