Please help. I really need a new winter jacket asap. For the last 3 years I have worn and loved in warmth a thick north face coat but it's a size 8 and getting too tight (I'm 22 weeks). I am in a dilemma. Do I get a cheaper outdoor coat in a size 12 or something or will that too be too tight in 10 plus weeks? I have a dog who I walk twice a day in wind, snow and rain so really need something waterproof and warm. Any ideas? I cannot afford another northface :(
