After seeing this months ago, I decided that I was gonna be Chell for Halloween! I've been working on the pattern for the past week and a half, and I have everything but the sleeves and collar all planned out. I've been using this and your other references as a basic idea, but I plan on converting the styles from both Portal and Portal 2 for my jumpsuit (meaning, I'm using the upper design from Portal, excluding the length of the sleeves, and the lower pants design from Portal 2)!! It's been so fun, but kinda stressful, to put together. I cannot thank you enough for uploading this, it has helped me tremendously!!
Just a quick question, How did you use to measure the sleeve pattern and the collar pattern? I want to make sure they fit right and I was a little stuck on the whole process...
I'm so glad it was useful to you! I'd love to see pictures once you finish.
For the sleeves and collar i would recommend measuring based on a collared shirt that fits the way you want. You can turn it inside out to see exactly where the seams are on the sleeve for easier measuring. The collar should fit your neck at the smaller end (right where the e is in the pattern) and flare out by an inch or two on the wider end. This can also be measured off a factory made shirt. If you don't have any collared shirts or none that match the pattern well, you could even just sneakily measure one in the store after trying them on for fit
Would be pretty easy to leave the piping out, since it's just stuck between each side of fabric before you sew.
As far as order: I would assemble the pieces of the shirt, making a ring with the panels around the waist and attaching them to the top of the shirt before attaching the sleeves. When you make the pants portion you'll want to sew up each leg, turn one inside out and put the right side out leg on the inside of it so the outside parts of the legs are touching, then you can sew the crotch seam together and turn them right side out again (maybe I should make a tutorial for that too ) The pockets should probably be added last so you can see where they will be on your body. Let me know if that makes sense, I can try to be more detailed.
