The Tristan is really very close to the Riley . VERY similar! It is basically the same leather, same zip top satchel design, same compartments, same feet on the bottom, only difference really, is the Tristan just has more silver hardware on it, which I really like. It might be too fancy for some because of the chain strap. Many prefer their bags more plain. Here is two picks of the front and side so you can see the extra fancyness of it. I think the large Riley is bigger than the Tristan but not by much. The Tristan appears to be midway between the medium and large Riley. It really is a perfect size, leaning more towards large. It is 16 L x 11 H x 5 deep. But both are gorgeous. The Tristans only come in Silver hardware. They have them in black, luggage, white, red, silver, summer blue , navy and fuchsia. So they do come in quite a few colors. They even have one that is python embossed.
Check out this summer blue! Isn't this pretty? I also posted a pic of the side so you could see the extra silver hardware on it. I just love that! It looks great while carrying cuz you can see it from the back of you while carrying. Is a real eye catcher! And see how the leather is folded up on the bottom? Just gives it more detail. I am one that appreciates detailing. many prefer a smoother look without all the detailing.
