Please, please tell me where you bought that Seras cosplay x_X I NEED to know. I've been looking all over for one like that and I keep finding cheap crappy knock offs ._.
the one you're finding is probably the one I have. I altered the hell out of one from mooncostumes.com mostly by hand because my sewing machine was broken at the time. I got the patches from someone who doesn't sell them anymore, unfortunately.
