老爹帽

Picked this up for my summer dress days, but it actually works just as well with a casual suit—the 100% cotton feels nice and breathable. The adjustable clasp is easy to use and stays put, even after a windy bike ride.

I've been wearing this hat with everything from dresses to gym shorts, and it somehow works every time. The adjustable clasp at the back makes it easy to get a snug fit without being too tight.

The cotton is soft and breathable, which makes a huge difference on warm days. The adjustable clasp is easy to use and actually stays put once you set the size.
