I use a PS1 in the large size as my everyday bag for school and I must say it's probably my FAVORITE everyday bag. It's so casual and convenient. I can fit all my books plus daily essentials with ease and have had no quality issues so far. The leather ages beautifully and is buttery soft now. The color does fade but in the way a Balenciaga would, and I think the faded ones look lovely.
If any of you guys do go for one, I really suggest the large size, medium is a bit small and the XL was way too big on me. I'm 5'7" and the large is just perfect. Here's a pic of the bag and a bad modeling shot lol!View attachment 3782020

I think it's a great mod shot and I love the color of yours but I still think the medium is best for me. I'm in the same boat as @prada_prince in this one. Thanks for weighing in on this though.
