Lust Vs. Must: The Leather Panel Shirt

left//right
It's been a while since I've done one of these posts! I honestly kind of stumbled upon this Lust vs. Must when I was shopping for myself. I have expensive taste. I'll be the first to admit it. Only issue is that well, it's expensive. So I'm TRYING to be good and look for alternatives instead of picking up the designer piece right away. I think this one is a pretty good alternative, if I do say so myself. Can you tell which one is the Lust and which is the Must?
P.S. The "Must" comes in other colors too. Yes please!
