The final version

I'm going to wink at Star Trek. The yellow dress I found is typical for the late 60's with it's experimental cut. The Star Trek uniforms are equally famous for original cut. Well, not the Star Trek Enterprise then. I don't want people to think "oh, that's a Star Trek dress" so I have decided to not do the two colour thing in the dress. I'm choosing a yellow fabric, but I'll cut the neckline in the asymmetric way Uhura and nurse Chapel's dresses are cut. I think that's the only real detail I need for those who knows their Star Trek to squee. The dress itself has a cut reminding you of a Star Trek uniform tunic from the early The Next Generation era so I really don't have do anything else.

 

I also found the colour scheme for the petticoat. It'll be a strong pink/raspberry red kind of a colour in soft tulle. I think I'm going to nick the idea to tie small strips of aqua tulle to the pink tulle, just like this tutu I spotted on Etsy. Without further ado:

I found the image below as a colour inspiration. I'm also wondering if I should find a polka dot ribbon, a rather wide one, to add to the tulle. I have to be careful though so I don't make it too full, because I'm not making a squaredance dress. I just want some ruffles because it's candy fun.
