new coat and boots for winter or emerald sgh city?

It depends on where you stand for the various items. Do you already have a few pairs of boots, just not from this season? If so, I'd get the bag. But if you don't like your coat or don't have a season appropriate one, then I think the coat is a must, and could be something classic that will last you for years (so in future you won't have to make a coat or bag decision!)
 
ITA! I'd get a vintage coat or one on sale and buy the bag. I get way more use out of a bag than a coat... but then again... I live in L.A. (not exactly coat weather).
 
if you really need a new coat and new boots buy them, and then start saving money for the bag, if you don't really need them choose what will give you more satisfaction
 
if you really, really need the coat and boots, go for it......

if you think it can wait, i'd say go for the bag...........

see, even i'm confused ;)
