The sleeveless turtle-neck is as versatile as the sleeved variety, and possibly more so, we suggest. Wear it under or over other layers or without any. Cover with a long cardigan or waistcoat; take it to tunic-length or choose a fitted style over skinny jeans. Pull it over a long-sleeved knit or give a floaty dress extra warmth without losing the feminine touch. Dare to bare your arms in a sleeveless turtle-neck and winter will slink away defeated.
