/cgl/ - Cosplay & EGL

So I've got a convention this weekend but, due to legit reasons, I haven't been able to exercise and I've gotten a little chubby. My cosplay was suppose to be a persona 4 one, but the girls are so thin. So I was thinking of using an old wig and the outfit and going as this persona4 character (pic). But I'm just wondering is it ok to cosplay a hamplanet when only slightly chubby? I can do tricks with the clothes, but my face doesn't really seem big enough (it's a bit long whereas her face is both fatter and wider) and I worried it'll look crummy. Should I just not cosplay? Or is there something I can do to make this work?
