When I went to Bimba & Lola, I really wasn't looking to buy anything - obviously that didn't happen -
I must give credit to the sales lady that brought out every bag that was in the store & in storage, until we found the perfect one*. It has a long strap & a short strap, the size is perfect because it fits my laptop but it's still not super large, the color goes with everything & the material is also slightly weatherproof, so I don't have to take extreme care of it...
I also ended up buying a make up bag for my sister - she found a better use of it though since it's now her pencil case
*I'm very particular about costumer service - it's something I pay very close attention to... do you?
