Very confused over clothing issues

My 8 y/o daughter has always had issues with clothing. On one hand she will wear only seamless socks, which she wears inside out because of the seam at the elastic edge. and she will not tie her shoes. She will only wear shoes which are big on her and has to keep them loose. Quite often they fall off. She can't stand tags and such and will only wear cotton leggings. Because of all this I start thinking she is sensitive to sensation.

But on the other hand she will wear a belt super tight over her leggings and even under her pjs. We had to take the belts away. Then she found some elastic headbands (about 2" thick) and will wear 2 of them around her waist. She would wear more but I won't allow it because it gets too tight and digs into her skin. Then 2 pairs of undies. She also will wear a bikini bathing suit top, then an undershirt, then a shirt all at once, even to go to bed. Lately for swimming (she's on a team) she has begun to wear underwear under her suit and a shirt on top of the suit.

Mostly on this site I only see one kind of behavior at once. Can she be both sensitive to sensation and need overload of sensation at once? Or is she just being impossible just to drive be bonkers?
