They aren't to my taste.
However, their Jade jeggings are absolutely the best jeggings ever. They do them in standard and long length and are the most comfortable and flattering jeggings for my awkward pear shape.
I was in House of Fraser today looking at expensive jeans, and the sales assistant complimented me on the ones I was wearing, which happened to be a pair of the navy jeggings. They are dearer than most brands, but they wear and wash extremely well. I now have three pairs.
And, no I don't work for them.
