How do you make your Cosplay?

As the title says. Do you buy yours or do you thirt shop yours or do you make it from base up or other way of doing it? What is your method of making your cosplay? Have you gotten more complicated over years?

I always used to buy mine, but I have a couple I've thrown together, but I can't sew, so I buy different things and wear them together. For the Yin - Darker than Black cosplay I bought a purple swing dress, wig, pink contacts and a black bolero. For Skip Beat! I found a pink 1970s jumpsuit and had the patches custom embroidered and had my mum sew them on. I have one costume that a friend made and my mum embroidered, and that's the Hatsune Miku - Synchronicity one. My friend made a whole under dress out of satin, and sewed lace onto the hem, and she sewed lace onto the corset. My mum did the chest panel and embroidery as well as sewing the sleeves and the lace around the socks. All I did was a bit of tack stitching ^ ^;

Some of my cosplay are bought and some are made by me when my sewing machine was still working :D while the props is made to order cause I don't know how to make swords and armor :D If you're asking about making cosplay well you can ask youtube about it but when a sew my cosplays (mostly skirts and fluffy dresses) I make sure to get my measurements, how many pleat will be done is skirts and allowance for the upper and lower part of the costume, also the ruffles will be a little bit longer than the skirts of where ever part you gonna pot it in.. oh yeah the hardest part is finding the right pattern of fabric for it thats what complicated about making it:D
