In just a short couple of weeks since I received them, these have become my favourite! I even prefer them to my nike, which is quite a feat. They are simply lovely. The sizing is spot on, and they fit me like a glove. Not too high in the waist, not too tight and with a string on the inside that can be used if necessary. The material is slightly sheer, and I find that this really accentuates my shape. The fabric is very breathable (though slightly less so than nike), and the tights are comfortable and stretchy. The seam also sits comfortably below the knee. I ordered the small, and they are probably closest to a UK size 10.
An all-round winner!
