Halloween Costume Help - Morrisville,PA

I would start with a tan body suit designed to keep me warm since it occasionally likes to snow on halloween. Then I would do the white nose, board shorts and a matching skin tight swim shirt. Add some sunglasses and some blond highlights to the hair.. Maybe get some foam board and make a surfboard complete with the cord strapped to the wrist ( you could do half a surfboard with the one side made to look like the shark bit it off)
Oh and don't forget to wear a sharks tooth necklace!!

Board shorts, maybe you could buy one of those "shirtless guy" t-shirts too (kind of like this: https://www.dresslily.com/short-sleeve-3d-muscle-pattern-..., put a Hawaiian shirt on top, wear a blonde wig, and carry a surfboard.

Long board swim shorts, swim shirt, zinc oxide on your nose?

That should be the easiest of the whole family! Vans or Keds, board shorts and a tank top. Some white out sunscreen on your nose. Maybe a seashell necklace or choker. Easy things to find at the thrift store if you don't want to spend a lot. Get some fake blood and have a "shark bite" on your arm or leg :-)

I like the ideas below - or you could do the wetsuit idea (or make it look like one with some leggings, rash guard and tee shirt ...) etc.

Super cute and fun family costume idea!
