Marc By Marc Jacobs Preppy Nylon Natasha. This is a fun way to brighten up a gray day, and of course it's in my favorite color: electric blue. The i.d. tag is detachable, and the inside is super roomy with two pockets.
Marc By Marc Jacobs Preppy Nylon Dakota. A slightly more professional version, and it also comes in black.
Louis Vuitton Pochette Milla MM. This is one of the few Louis Vuitton bags I could find that was totally vegan. I think the chain is cuter than a leather strap anyway.
Marc By Marc Jacobs Eazy Tote. This one is nice and big for all your stuff and surprise, surprise, it also comes in blue.
