Do te have any ideas for Noah homemade costume?

Maybe te can try to find clothes that look like o kind of look like his clothes, te can get a dark brown wig ( if girl wig, then cut part of the wig off to look like Noah's wig ) and idk what to do about the skin, unless she kind of has the same color o close to his skin color, that's all I can think about. I hope te can find a good way if this isn't helpful enough.

Find someone who is inclined at sewing in your family. Make sure te have the clothes. Remember that Noah's undershirt is buttoned up, so it might be best to look in your dads closet... For stuff...
