Place to Find Slim Fit Tee and Quarter Zip

Hi everybody so currently i am trying to buy some new clothes and I want a shop (online preferred) that sells slim fit/muscle fit. I am like 5'4 and i am a bit thin. So finding one is pretty hard i need one under 3500 LKR, so far the only luck i have had is with NEXT but there xs is unavailable. Also i need a black/blue quarter zip for the same size it would help if it was under 5k. Thank you
