My 1940s style Star Trek dress is finished! I am looking forward to wearing it to a 1940s party this weekend. (I will post pictures of the event next week).
To summarize, the dress is made from 2 layers of rayon challis. The neckline is piped and has several gold buttons for “pips.” 
I modified the Dahlia blouse pattern from Wearing History. I added in the extra seams in the front and back to create color-blocking and drafted the skirt myself.
The front is gathered at the shoulders with a puffed sleeve head.
The elbow is gathered, like many 1940s dresses, and the sleeves are extra long.
There is a curved seam where the bodice meets the skirt.
The rayon makes for a very nice, drapey dress. It is very form-fitting, especially around the hips. I’m afraid the construction shows off every bump and lump so proper vintage undergarments are required: a Rago girdle and a slip.
The dress closes on the side with a side-lapped zipper, hand-stitched in. (Originally I used invisible zippers, but this is more accurate to the time period).
I actually thought I completed it a few weeks ago, but when I put it on I wasn’t completely pleased with the way it hung, so I redid it – twice. Originally I made this as a 2-piece outfit, with a somewhat A-line skirt. I decided to change to a pencil skirt, which I felt would work better with the top. Also, I converted the outfit to a one piece, thinking the skirt would weigh down the bodice and keep the edges from flipping up. This meant I had to completely dismantle and recut the skirt, and remove 2 zippers.
Originally I prick-stitched the bodice to the skirt, which made the peplum front stand out, but the back looked a little odd. I took the dress and zipper apart again, and stitched everything together. There’s still little things I’m not 100% happy about, but overall I am very pleased with how it came together!
Final cost $87.93:
- From Fabric.com: 3 yards black rayon challis, 2 yards mustard rayon challis, 1 spool black thread ($41.10 including tax and free shipping)
- From Wearing History: a digital pattern bought on sale (I highly recommend you pay to get a paper pattern instead; I bought mine digitally because I needed it right away, but the paper ones are worth it!)
- From the stash: gold buttons and zipper
- From Thinkgeek: TNG communicator pin ($19.99 plus $6.95 shipping)
- From Amazon: TNG phaser ($10.89 plus free Prime shipping)
I especially pleased with the communicator. It’s a quality reproduction that is on a strong magnet so I won’t get pin holes in my dress. The communicator is now available on Amazon (affiliate link) so if you have Prime you can even save on the shipping:

I bought a TNG phaser just because it was fun and cheap. (It makes noise!): 
I purchased some incredible Miss L Fire shoes, but sadly they are a bit big for me. I might see if I can get some inserts that won’t show in the peep toe, but for now I’ll have to wear plain black pumps with the dress.

I also own these Capezios, which are very comfortable dance shoes, so they might be better for the event I have in mind this weekend anyway.

Read Parts 1 and 2.
Next step is to figure out how to do hair and make-up, which are not things I excel at. Wish me luck!
