I started this topic as a show for hot cosplay women, but I was really impressed with this costume:



From "I Challlenged GROOT, the Monster From Planet X", a Lee/Kirby/Ayers
story from TALES TO ASTONISH 13, Nov 1960.

Byrne also did a retro-story that referenced the character (and the whole pre-Marvel
monster era) in FANTASTIC FOUR 271-273.


There's plenty of other really nice costumes, and quite a few attractive cosplay
women on the same page:
