I want to find some plain black jeggings, like these ones that topshop do:

http://www.topshop.com/webapp/wcs/stores/servlet/ProductDisplay?beginIndex=0&viewAllFlag=&catalogId =33057&storeId=12556&productId=1509340&langId=-1&categoryId=&parent_category_rn=

(i know that it says leggings on the website, but they look just like jeggings - there slightly thicker)

but i want them in plain black. but the only black jeggings i can find are all made of a sort of denim material! whereas im after a thicker cotton sorta material! and i dont want plain black leggings, because i find leggings slightly too thin. can anyone help me? im looking for high street clothing, anything from topshop, new look, warehouse - all those sorta popular stores will do. and please be specific!
thank you so much!

Ahhh I see, okay so can anyone help me find thicker cotton black leggings? If you look in the picture of the blue topshop ones, they're slightly thicker - I want ones like those!
