Get a robe too! Preferably one that at least goes to your knees if you walk fast. For your caddy, get a mesh one with a hook because you REALLY don’t want communal br water leaking onto your feet while you walk back to your room, and easy access through a shower curtain to all your things. Also get a floor mat, so that all residual water from your shoes and caddy will not be on your dorm floor.
