ok so this is like a basic...right?  
yet i don't have one.  
this last trip to NYC i was looking for one, but i just couldn't find the right one for me.  (maybe i didn't know where to look)
i went to the burberry store, since they pretty much invented the damn thing, and even with Prorsum, I couldn't find the right one...plus i wasn't about to spend $2000 on a trench coat...suit maybe...trench coat, NO!!!!
i know that if i was in Tokyo, i would be able to find exactly what i'm looking for, but alas i'm here.  any brand recommendations.  i know they aren't supposed to be extremely tight around your body, but i'm a skinny little thing and everything i've tried on so far i feel like a little girl playing with her mom's clothing.  
i'll look online for some pics, and hopefully someone can help out.
