I added the tag straw_hat, though I am sure there is a better word for such hats.
Wikipedia says it could be a takuhatsugasa. At least the example looks like it.

Is no one going to mention Byakuren's giant straw hat? Was Zun compensating for Byakuren being hatless before?

It's a perfectly normal hat for a buddhist wandering monk. Just be glad it's not a hat of the Komuso Buddhist Sect.

Going by tag edits by ghostrigger on earlier images of Myouren, I'd say it's an ajirogasa. That's also what it's called on the Japanese wiki. The English wiki says takuhatsugasa, but since "takuhatsu" means "monk's "begging" ", I assume that's a term describing a wider variety of hats.

But Byakuren doesn't have black stripes in her hair. Its shading and shows of her purple hair

It's because these hats are also used as baskets, for offerings. These offerings are mainly of food for the monk.
On a side note, those Tengu Hats are also used by some monks (shugendo sect), and their second use is as a drinking cup. Now why isn't this used in pictures?
