search for the perfect vegan leather bag

i know this doesn't seem like a big deal, but it is! i cannot seem to find a handbag NOT made of leather that i actually like. matt & nat is a great vegan leather handbag brand, and i found a bag i liked from there, but once it came in the mail, i realised it's a duffel/travel bag! simultaneously, i ordered a bag from this brand un apres-midi de chien which is made out of nylon but it was too small!
see, i need to fit my laptop (15") into my handbag which i carry around with me almost everywhere. so i need something that will fit my laptop AND the rest of my junk and will also be adequate to carry around without my laptop. 
sounds superficial. but its just not easy to find the right bag... right now i have a leather bag, but as a vegan i am on the road to purging all my leather bags and shoes etc. all the other vegan handbags are made of materials like hemp. yech.
