Def be proud of your bag, gosh darnit! I'm in Electrical Engineering, so there are only a handful of girls, and rarely are they very "hip". I was doing an internship once and the guys always joked around and playfully picked on me about my dooney, which is by no means an LV, but still over $100. Men rarely care about that kind of stuff and sometimes don't know anything about it, so I'm pretty lucky that i might stand out, but i'm going to stand out regardless! As for other women, I can kind of feel your awkwardness because women DO care about that kind of stuff and can get catty. It's a crappy situation with jealousy at the heart of it all. It's a purse! There are much more pressing issues at a workplace than a bag.
