Crossbody bag for summer city trip

Hi.

I’m searching for a Crossbody bag for a summer city trip which is a bit bigger and wider than the Michael Kors Jet Set Crossbody and has a wider shoulder strap than the MK.
About the color I’m unsure. Mostly of my bags are black, but I think for summer a lighter color would be better. Budget: not more than 300 $.

I really don’t know where to look or which brand is popular? 🤷‍♀️ Do you have any suggestions for me please? 🙏
