Star Trek Costume
Sources
Many people write to me asking where to get patterns
and accessories for your Trek Uniforms, so here are
some website's and or info on sources for Trek

RODDENBERRY.COM
(formerly LINCOLN ENTERPRISES)

Carries all the patterns and the most  authentic accessories
like comm badges, rank insignias & official props. This store has been
around for over 30 years and was the first Star Trek store created by
Gene himself and run by Majel and now Eugene.

PROP REPLICAS

Roddenberry.com
Sells replicas from all the series, but you have to act quick..they go
fast and are not available till the next batch is made.
