A black heat tech sweater/undershirt is one of the most versatile clothing this winter. Heattech Undershirt from Uniqlo can be worn on its own or under a thick sweater for extra warmth. On warmer days, I pair them up with a faux-fur vest for a temperature perfect outfit.
Faux-fur pieces may make you look bulkier or chunkier - for a fitter look, you can add a thin belt or anything to string around the waist line.
For a day around the city, I switched the heel booties for a pair of Nine West flat booties. I explored around Central Park for a whole afternoon and fell in love with the tree root doors at 1 Hotel Central Park.
