What you would expect at a Vera Wang show: Light, diaphanous chiffon dresses thatfloat like ghosts. What you wouldn't expect at a Vera Wang show: Parkas. This morning at Lincoln Center, Vera Wang gave us both, and for some reason, the combination worked. Starting her show on the dark side, Wang offered up fur-trimmed anoraks along with what has been one of the big mysteries of the week -- sleeveless coats. Do women's arms no longer get cold? But the practicalities of winter were not weighing heavily on Wang's mind during the second half of her show when she paraded our her delicately pleated gowns in seasonally appropriate shades. She showed a stunning range, from youthful and tough to light and feminine, and even mixed the two wonderfully.
