Asw someone said above, I think the Latin Mass is bringing back the hats, veils and decent dressing for women.
The Latin rite institutes an attitude of decorum.
Indeed, most (not all) of the ladies at my parish’s TLM are covered. Most choose veils, and from what I understand, the online chapel veil business is booming. Even a short perusal through eBay will offer a bumper crop of new and vintage veils, from the doilies right on through giant Spanish mantillas.
This doesn’t even count the direct online businesses that sell veils. In addition to eBay and a Catholic goods store, I’ve purchased mine from both an importer of flamenco dance supplies AND an Orthodox Jewish headcovering business.
