Free Engineering Radiation Suit Pattern!

As you’re probably aware, I recently had the privilege of studying a screen-used engineering radiation suit, courtesy of Ray Minarcik.

In addition to thoroughly documenting the costume’s dimensions and construction, I actually extrapolated a sewing pattern from it, using a technique I learned from a book called 101 Sewing Secrets from the Singer Sewing Reference Library.

Basically, this process entails pinning or hand-basting a layer of muslin to the garment and lightly tracing the seam lines (etc.) with a pencil.

I did this for all the jumpsuit body panels!

I then transferred my muslin pattern to my dot-and-cross pattern-drafting paper, “true-ing” all the seam lines with the various rulers needed and double-checking everything for accuracy.

Then, I added all the appropriate seam/hem allowances to the appropriate edges and traced the pattern onto the large sheets of paper I usually use for my Tailors Gone Wild sewing patterns.

I’ve since had it scanned at my local copy/print shop, given it a good polish, and digitally labeled it, so it’s all ready to go!

You can download my traced pattern here for free.

The pattern is a PDF, comprised of two large pages.

The first page is 36″ x 72″, and the second page is 36″ x 48″.

A few notes on the pattern draft:

  • The finished jumpsuit measures approximately 42” around the chest and 36” around the waist. It appears to have been intended for a wearer approximately 6’ tall.
  • As you may recall from my costume examination, some of the specific seam lines were subtly asymmetrical. I took the liberty of making these seams symmetrical – both for my convenience, and for yours. πŸ™‚
  • As you may also recall from my costume examination, the specific seam allowances occasionally tapered; I preserved (what I believe to be) the allowances as originally intended, evening them to the shape of the finished garment.
  • The exception is that the original upper center front seam allowances were 1 ½”, but they’re reduced to 1” on this pattern.
  • I straightened the lower back rectangle to consistent dimensions of 9 ¼” x 3 ½”.
  • I also straightened the thigh and sleeve tubing panel assemblies.
  • The upper center front, side, and inseam allowances are all 1”. The shoulder seam allowances are ¾”. The sleeve and front panel seam allowances are ⅝”. The armscye and crotch seam allowances are ½”. The neckline hem allowance is also ½”. The pant leg hem allowances are 3”, and the sleeve hem allowances are 2”.
  • This traced pattern is VERY close to the original, but you’ll want to allow a tiny margin (say, about ⅛” in any given direction) for β€œhuman error.”

FYI, this is the exact pattern I used as a base for my graded Tailors Gone Wild engineering radiation suit patterns.

Anyway, I hope you enjoy the free pattern. πŸ™‚
