The Etsy designer behind Beyoncé‘s fabulous disco-style cowboy hat now has firsthand experience with the Bey effect … after the Renaissance tour announcement forced her to shut down her shop.

Abby Misbin AKA “Trending by Abby” on Etsy, tells TMZ … a stylist for Beyoncé hit her up way back last June, saying she wanted a mirrored cowboy hat for Beyoncé and would need it in 5 days. Abby says she was thrilled to handmake the hat for her and sold it to her for $215. Talk about a bargain for the likes of Queen B.

Well, about 2 months later Abby’s creation showed up in a Beyoncé video teaser … but even that promotion didn’t compare to what was to come.

Abby was pleasantly surprised to see Bey rocking the 10,000 to 15,000 mirror-tile hat once again this week when she dropped her “Renaissance” tour dates.

Abby says that was the tipping point … she’s been absolutely bombarded with orders from folks trying to get their hands on the same hat. She usually gets about 5-6 orders per week, but in just one day she got 60 orders!!! The BeyHive wants what it wants.

Normally she can only make about 2 of the hats in a day — there’s a ton of detail because they’re handmade — so, Abby’s had to shut down her shop for now.

This is certainly on brand for the BeyHive … ICYMI, fans went crazy after she released the dates for her highly anticipated tour.

Going forward, Abby says she’s working on fulfilling orders with her sister’s help before re-opening her Etsy shop.
