I feel like there's no one specific place you should buy clothes. If you don't purchase them before you come to Boston, Newbury Street has a lot of shops where you can purchase things like this. Things to buy: Boots that won't slip on ice, winter coat, hat, gloves (the ones that can touch your phone are super nice too). Other than that, just have some layered or long sleeve outfits for extra warmth. I feel like that's pretty much it for clothes, but if I'm forgetting something, OFY holds an event over summer? or fall? of like 'How do I Prepare for Boston Winter', so recommend that if you're worried about it. :) ~ Katie
