Is there a mens retro clothing category?

HI Victoria. No, unlike in womans, there is no specific Men's vintage and retro category

To find them about the best you can do is add the word vintage or retro to your search and capture those sellers who have added that word in their title or description.

This has annoyed me in the past too, If there is a Ladies Retro category there should also be a mens! We like to rock vintage fashion too!

This is and has been for a long time a very much needed Catagory!
