This is got to be the 20th variation of the same theme "Asian guy from a tropical country going to Boston for the winter and need...." advice on scarf, gloves, cashmere sweater, wool socks, top coat, what color scarf, what color socks, what color gloves, what color sweater, what style sweater, where and how to get them cheap......
Jose, you need to relax. There's no need to plan your purchases from 9,000 miles away. You have plenty of time to make your winter wardrobe purchases once get to Boston from a tropical country. Once in Boston, go to Filene's Basement, try the clothes on, look into mirror, feel the material, compare different colors then you'll know what material you feel comfortable and what style and color looks good on you.
Ask what style to get, you'll get 10 different answers from 10 different people, the bottom line is you need to decide for yourself what looks good on you, what makes you feel comfortable not people think what would look good on you, make you feel warm.
It may be worthwhile for you to make day trip to Kittery outlet center (only an hour away from Boston). They have Polo, Brooks Bros., Eddie Bauer, BR, HF... all good sources for winter clothings. They even have your favorite brand Van Hausen outlet there.
