I have loads of pairs of leggings -I wear them all the time -like pasta said with sweatshirts, t-shirts any kind of top but always with knee high boots of which I must have at least 7 different pairs.I have ventured with wedgy sandals and a top during the summer always past my ass-looks funkier that way.
I have jeans -im just not comfy in them for any length of time.I like the long top leggings boots look -its my signature dish of sorts.
Geordie -your jeans will look smashing on you but leggings are ace for dossing about in :)
