First you'll need 1 1/2 to 2 yards of shiny liquid gold lame' fabric (fabric content 100% polyester), about 4 yards of black (or white) 3/8 inch wide elastic band for each of the 2 leg openings and the neck opening, a spool of black thread, a pair of well sharpened scissors to cut the fabric, and of course a sewing machine.

You can use this as a guide (minus the measurements), or if you're feeling a little or too lost, you can combine the pattern of a tee-shirt you wear and a pair of panties with elastic leg openings that you wear, cut the tee-shirt at the seams and cut an inch or so off the collar area of the tee-shirt as the bodysuit's neck opening is gonna be using elastic anyways, and use that for the measurements of the top part of the bodysuit and sleeves, and take the lingerie elastic off the panties using a thread ripper , cutting the panties at the side seams and using the panties pattern for the bottom part of the bodysuit! But before you do that approach for measuring, make sure the bottom of your tee-shirt and top part of your panties meets all around as if you decide to use that for measurements and patterning, you'll have to remember that the leotard bodysuit is a one-piece clothing item!

To make measuring for the main part of the leotard bodysuit pattern easier (minus the sleeves, here's a human diagram which I used windows paint to draw the pattern into! Use this diagram for refrence when measuring your own or someone elses size! Notice how extended the tops of the shoulder straps and crotch bottom are relative to the human drawings! Use that as a guide for this particular bodysuit/leotard design (especially due to the fabric content of the leotard/bodysuit)! The drawing represents the leotard/bodysuit pattern using the 100% polyester liquid lame' fabric that's used for the leotard bodysuit! Note the colors!

Blue=leotard/bodysuit pattern drawing scetch. (note the double blue lines! They represent the fact that these edges needs to be folded inward towards the fabric backing!)

Red=The areas that will require the elastic band to be sewed in.

Black=Of course the drawing scetch of the human body. (drawed by someone else, of course!)

I hope this makes measuring much more simple! And remember, if you make the elastic loops too big or too tight for the leg and neck openings, you can always use a tool called a thread ripper or seam ripper to slowly and carefully rip the thread out of the elastic openings and remeasure the elastic loops again. And also, if you need, you can adjust the cut of the neck opening/ arm openings, and/or leg openings (thus making it a bit bigger or smaller)for comfort if needed! This scetch drawing is just a rough idea of what the pattern should be like (sizewise) relative to and compared to the actual human drawings!

Remember when you go to do the stitching work on your sewing machine to follow these two guidelines on this pic when you sew!

And also remember that the fabric used in this leotard/bodysuit design stretches only horizontally and won't stretch vertically, so remember to make sure the panty-bottom portion of the leotard/bodysuit is at least twice as long from the hips to the bottom as it is from your hips to your crotch! Also make sure the measurement is twice as long from the bottom of the arm opening to the shoulder top and that the neck opening is at least 1.5 to twice as long on the back side and 1.5 as long on the front side (neck opening)!

Now we go to sew the side seams together, this making sure before you do that the metallic liquid gold sides are touching each other on both fabric peaces!

Now (using the line drawing on the pattern) you need to fold the edges inwards into the black side of the fabric twice and, using a straight line sewing style, sew the edges in, so as to prevent the fabric from running as this fabric is prone to runs! Then when that part is done, then you measure three pieces of black elastic and measure from your outer shoulder blade minus a couple inches for the elastic for the neck opening and (if needed) the circumference of the leg opening of any panties or undies you have for the leg openings! Then you'll need to sew the black elastic into loops and sew the two evenly sized elastic loops into each leg opening (first stretching the loops from inseam to inseam on the leg openings to even it out) and doing the same thing for the neck opening!

When doing the elastic, remember to make sure the circumference of the elastic is about half to 1/3 that of the un-elasticised neck/leg/arm opening!

Use this drawing to give you a rough idea of how to stretch the elastic for the neck and leg openings!
And always remember to make a small sewing four times in equal measurements per opening of the neck and leg openings and to make sure the elastic band is hidden (by sewing it onto the edge of the openings on the same saide of the fabric as the inside backing)!

(Note that black equals the physical leg and neck opening and blue euqals the elastic band loops!)

Then when you're sewing in the elastic, remember to stretch the elastic band as best as you can when sewing in the elastic band into the edge of the leg and neck openings!

(Please note that the Elastic is not needed for the arm openings as that's where the sleeves will be sewn into!)

Now comes the sleeves! If you're using an old tee-shirt for the sleeve measurement, you'll need to cut the sleeve at the seams and use it to measure the size of sleeve and use it as a guide to cut the pattern on the 2nd yard of the 100% polyester gold lame' fabric. do it twice, though, as you'll need 2 sleeves of the same size and measurement! Now go ahead and sew the sleeves together and sew it onto the leotard/bodysuit!

Now after all is said and done, the entire leotard/bodysuit should look something like this! (This one showing the gold one!)

Here's a picture of the same design and fabric choice, but in liquid silver lame' (sitting next to a pair of shiny liquid silver lame pants made of the same kind of 100% polyester liquid lame fabric).

Another one using the same design and 100% polyester liquid lame' fabric fabric choice, but in lighter silver with a white backing!

And yet another one using the same design and fabric choice, but in shattered-glass like silver sparkle lame'!
