The old-time special effects from the original Star Trek were replaced by the incredible CGI effects in the movie reboots, but the classic uniforms stayed pretty much the same. There was no reason to change. The Women's Star Trek 3 Uhura Costume is a timeless mini dress style. It is red and features a Starfleet insignia on the chest and is designed to look like the one Zoe Saldana wore in 2016's Star Trek Beyond.

She soon became a role model for women of all colors and Zoe Saldana has taken over that honor and responsibility in the reboot movies. You can carry the mantle too when you put on this iconic space uniform.
