Cut out the fabric and review the pattern. Make sure you keep in mind the direction of stretch when you are laying out your pattern pieces.

Follow the dress pattern. Just start sewing the dress together according to the pattern directions while keeping the Star Trek details in mind. What you want to consider is when it comes to the neck area or the bottom of the sleeves would this it be better to do this step now or should I add in the detail (black collar or gold rick rack trim) now.

Add a black collar. You can add the collar at the end just like you would do for binding. If you pattern doesn't have binding on the collar just fold a 4 inch piece of black fabric in half lengthwise. Sew the short ends together. Next iron it in half you should have a skinny black circle (you'll want the size to be about 70% the size of your neck opening and make sure you cut it out of stretchy fabric) Then attach the collar to the dress neckline by pinning the raw edges of the collar to the neck line. You'll need to stretch it a bit to make it fit. This will help the neck hold its shape.

Add gold rick rack. For the sleeve details you can sew the gold rick rack on before you close up the sleeves or just after. Be for is easier since it will be a flat piece but it's not too bad just to sew it once the whole thing is done.
