Since I began cycling in earnest I have become a big fan of leggings. Not just those in lycra, I'm taking about ones you wear in every day life.
Black leggings with a long jumper/t-shirt transfer beautifully from bike to going out and I even own a pair of black calf boots bought specifically for wearing with leggings. I also own a couple of pairs of crazy tights. They're thick and opaque but one pair has a stripes in shades of grey while the other has a fabulous ribbed pattern. All well and good.
However, I was recently having a wander round M&S when I realised to my horror that the new leggings I was considering, were in fact, jeggings. Leggings woven with a pattern to make them look like the skinniest of skinny jeans. And I was actually considering buying them.
I have fairly good legs (I have been complimented on them) and they would be immensely practical for cycling as they're completely opaque but I'm unsure.
