>>4040015I think it'd be fine if the amount of poof was the length of both arms, imagine someone standing straight up with their arms straight (t-pose) from a birds eye view (as seen from above), the skirt part would fit standard doors if it went to the elbows but if you also factor in dresses are made from malleable materials that can be pushed in and fold very easily you can go to... let's say a little past the finger tips without too much trouble for every day though you'd have to be aware of your surroundings but you'd be able to get by just fine just be cautious around fragile things
though I'd say the ideal poof for every day would be akin to madoka's outfit and you have the big ones for special occasions where you don't really need to be in a hurry and you aren't planning on going on adventures though murky swamps with sticky mud.
