So for my daughters 12th birthday she wants to go to her first Anime convention, and both of my kids want to cosplay. The problem is, I couldn't make a costume from scratch if my life depended on it and I'm having a hard time finding pre-made in their sizes. I was hoping someone could give me some info. She wants to be Wendy and he wants Natsu. My kids are petite, My daughter weighs just over 60 lbs, and my 9 year old son is at 50. they are healthy, but their metabolism is insane. Thank you in advance!
