Hello! This is a general question (open to answers from anyone) about how to sew pants with a lining to make them poofy. Specifically, characters in Kingdom Hearts. I’ve been wanting to cosplay Ventus/Sora (KH2) but I’m not sure how to tackle the pants. Would I just sew a second layer of pants minus the fly/panel etc., then sew the leg ends together and then fill the pants with batting/foam and then finally sew the top/waist up? Idk how I would sew the zipper in though with the bat/foam in it.
Lining the shorts to create extra space for the poof is a good idea, as is stuffing it, especially if you want a very stylized and cartoony look. Batting would be a better option than foam for this, since it can more easily conform to the poof of the legs (and create the bit of heaviness seen at the bottom of the pants) without needing to go all the way up to the waistband, and without too much added thickness that isn’t as compressible. Another option, especially if you want more poofiness towards the bottom of the pant, is to gather long strips of tulle and sew them into the bottom hemline, between the shell and the lining. This is a technique often used to keep large puff sleeves poofy, and may help you here.
