I am in love with these. bought the regular length last year and loved them despite the shortness (hit right above the ankle). that length looks good with ballet flats or tucked into boots. this year i bought the burgundy and the teal in the long length. i am 5'7" and the long fit perfectly! they come to the bottom of my ankle without extra fabric. 
please restock the "carbon" in the long length! i want to buy my 4th pair!
