I need some halloween costume help?

ok well im being misty from pokemon, im getting a yellow tank, short denim shorts and red suspenders then im dying my hair red and putting it to the side. or you could be a crazy mental person if u get a white shirt and have someone pin it to the sides for, but u wouldnt be able to move your arms lmfao, or u could be a sesame street person and just look for a shirt like elmo that has the faceon it and just get same matching color pants. u could also be like the person from the video on youtube shoes, that would be kinda kool. ummm yea thats all i think of
