Antonia-both you and the bag look adorable! I'm glad you posed with a coat on, since I'd be carrying the bag in a colder climate. I'm thinking about getting this bag but wondering if it'll fit a 15.4" laptop and still have room for everyday purse items without look like a bag about to explode. Since you have the bag, is this something you can answer?
When I say the bag is huge, I mean huge! My laptop is about the exact same size as yours and I know it would fit in the bag without any problem and still have plenty of room to spare! Maybe I'll try to actually put my computer along with my other things in the bag and see how it looks.....so I'll get back to you later with a better answer. The only thing is the bag doesn't have much structure, it's super puddly when empty so you may see lumps and bumps-I don't know how you feel about that. I think if someone needs to carry their laptop with them, they should have a more structured tote bag, IMO.
