Posting some pictures here for a visual... Here are the purses in my rotation (and those that just got removed from the rotation when I switched to a Macbook16)
1. Goyard Artoise MM - fits perfectly, and more space for a portable monitor, ipad, cables, essentials. Plus the zipper really make it more convenient. I haven't gone lengths of using this bag so I don't know how it will handle wear, and I am also unsure of its durability yet
2. Louis Vuitton MM Neverfull (epi) - fits as well. I really don't have any issues here, I believe in LV's durability. It's sort of a favorite, I am just looking for more variety.
3. Louis Vuitton Neverfull MM (monogram) - same thoughts as #2
4. Proenza Schouler PS1 Large - I love this style, but this just fell out of my rotation due to the tightness of the space for an MB16. As you can see it will fit, there's just no space for others.
5.
MCM Backpack - also fits, but it loses the shape when you fill it in with more stuff.
I hope this helps you with your search!
