Spiders in Australia occassionally hide in clothes, they use it as a form of shelter. I've been bitten 3 times by Huntsman spiders hiding in my clothes, they're not poisoness, but it's annoying.
Today this was hiding in a shirt I put on. It didn't bite me, just crawled up my back, out my shirt and jumped off my shoulder onto the floor where it then crawled up my stairs banister.
Obviously I took pictures, caught it and took some more. There's no size comparison, but I would say spread out it was a good 7-8 inches. cockjoke.
Oddly enough it was on my back/in my shirt for a good few minutes before it moved.
