Yes this is real.
Yes that dress is for men.
Yes that is a dude in the picture.
Gucci's description says:
This tartan smock in delicate colors reflects the idea of fluidity explored for the Fall Winter 2020 fashion show, disrupting the toxic stereotypes that mold masculine gender identity. The contrast Peter Pan collar and smock embroidery on the front add a childhood inspired element, which ties to a recurrent theme of the collection.
Perfect: Fluidity. Toxic stereotypes. Masculine gender identity. And children thrown in there for good measure.
Here we are now, humanity. We're making Little House on the Prairie dresses for dudes and acting like it's mentally unhealthy to think there's anything wrong with that.
God help us.
