Patricia Nash Small Bag
This is a super beautiful bag, unused too! It comes with 3 different straps (sorry only 2 are pictured) - 2 are embellished and they are both about 47 inches long, the non plain strap is 34 inches long. The bag itself is 8"x11" so not big enough for a full size laptop/macbook but you can fit a lot of stuff inside (such as notebook, tablet, phone etc). I'm not entirely sure if it's leather but it does seem like leather!
