The main appeal for me here is how low-key and anti-status-y these bags are, and how durable too. This quilted one from Clare Vivier has such a good chevron pattern.
This is the ideal size (for me at least) for days I’m not shlepping the laptop, and it comes in a couple of good camo prints—and black of course—too, but I like this rich blue.
A Longchamp tote is a solid, classic choice.
This bucket bag has a utilitarian vibe I can get with.
And here’s one that would be suitable for the office, I think.
