Got the pieces for my Cooking Mama cosplay yesterday.  I'll probably carry around my DS and a cheap spatula with it.  The aprons have nice deep pockets that I can seal with Velcro.  As you can see in the picture below, Mama's hair is pretty short.  Would do the hair, but I'd rather not wear a wig.  Maybe I can curl my hair up a little bit, but my hair is so long that I think it won't stay in. 

It really is an easy closet cosplay to do - not very many parts to it.
