Yup! I have mine in its box, and she stays under my bed! You may have room for it, depends on the size/layout of your room!

I had mine with me but I never got a chance to wear it around. I am pretty sure i wouldn't have felt comfortable doing that considering a friend and I got heckled once when we wore tails.

I've done a lot of college visits and seen what dorms look like, most of the ones I have seen have enough space to hold a tub to keep your fursuit in, depending on how many you have.

Uhm I never had them when I lived in a dorm but I do take all four of my suits with me to college with me! I usually keep the pieces in those plastic bins. I keep my heads out all nice and neat on a table, three out of the four of them have big ears so i'd need more bins than i'd know what to do with if I put them all in bins!
