Here are some dresses/robes that are actually cut for the male body. A lot of the examples are formal wear, because men are fucking pussies and don't wear dresses casually because they don't want to wear clothes similar to women.

Indian engagement/wedding attire. Simple and classy.

Billy Porter at the Oscars. Look at how it accentuates the triangle shape that a male torso has.
Shit like this though, is absolute trash.

No form, it doesn't highlight any features of his body when it's tight fitting. Wack, but not as laughable as a troon wearing women's clothes.
A really good example of how the same piece of clothing can be altered to look good on both men and women is the Japanese yukata. For both men and women, the yukata is sewn out of rectangular pieces of fabric. In men the sleeves are completely stitched to the body, but it does not for women to make space for the obi (sash/belt). The obi is thicker for women and tied at abdomen and is thinner for men and tied at the hips/waist. These differences are crucial because they compliment the natural forms of men and women's bodies and thus allow a blocky robe to look nice on both men and women.
Halfway in writing this post the editor didn't allow me to attach photos so Google "yukata men and women" to see what I'm talking about.
Men totally could pull off dresses like women. The first step in doing that is realizing that men are not women and design dresses for men from the ground up instead of trying to copy women.
