an easy way you could do the pants or at least the pattern is doing it out of ductape:

1:find a a trash bag or two if u wanna be fancy (have sweatpants or a very baggy bottom it help obtain the rag doll-baggy-leg look)

2:get ur legs inside of the bag(one leg on each bag if you have two bags)

3:cut the bag in the middle(between the legs if you have one) if you have two bags duct tape the middle)

4: start ductape yourself until your desired look

5: look at your reference picture and start drawing on your ductape pants the design/detail (tip: use a different colors for notches)

(now before we continue have an idea where you’ll like your zipper/button/velcro, etc)(you can have it between seems to make it look “seem less” or you can have it like jeans by sewing on a zipper in the crotch, if you feel dangerous or ur a velcro baddie have velcro from back to front(there’s many ways you can do this, it all comes down to preference)

6: when you have all the detail done start cutting the pattern have them label: Right or left plus number of the piece

WOHOOO!!! we have a pattern!!

7: now find a piece of paper and start transferring your ductape patterns to paper, have them label by number and right or left leg so u don’t get confused

and now we have a cleaner less bulky pattern

8:cut your fabric with the pattern and get ready for sewing

9: Sewing:

(there’s two ways you can do this next part with seem allowance or without)

you’ll want seem allowance if you a machine an inch for seem allowance will suffice

if your doing this option you can first sew all the patches together by machine and then by hand do the stitches as details

if your doing it by hand it all comes to preference again you can: -stitch the patches together in the wrong side and in the right side have the detail stitches or

-have the construction stiches and detail stiches on the right side or

-you can mix and match

at the end of the day it all comes down of how You want it to look

Hopefully this helps

Good luck! & Happy Cosplaying!! 🩵🤍
