Rate my essay? is it grammartically correct?

I liked it. OK, "grammartically" isn't a word, so you get a for that. Two tiny errors which I detect, one "...city, leaving its residents...' needs to be the possessive its' with the apostrophe...even the nazi didn't note that one. And, ho-hum, yes it's wear, not ware. btw, I like 'jostling', because, dammit, they DO try to hit each other! And they DO get physical inside! So there! Oh, and you may have intended 'a', but typically the role of a fashion maven is to keep others 'ahead' of the latest trends...a would be to keep them along side...while not following, not in the lead either. Hope you enjoyed your (s).
