Found on Reddit this photo of #pride in #Guadalajara, Mexico. Not sure when the photo was taken, but it was probably in 2018, since I see other photos with these dresses from a 2018 article.

I found another picture on Guadalajara Pride's 2018 coverage of the event. She is dressed in the #conchero outfit, a dance probably originating from the Chichimecas in northern Mexico.
The dance is a curious syncretism of several different traidtions, and I've never quite figured out exactly what those are. This picture is adding another modern ingredient into this cultural mix.
