I just saw a Levi jeans commercial which depicted a group of men taping shut all possible seams and holes in between all articles of clothing on one of the members of their group. Then they proceeded to fill his garments with helium and the gentlemen floated off of the ground. I realize that clothing is porous and the helium would be able to leak out. However, if the person in question were able to completely insulate him/herself and then fill the insulated area around their body full of helium, would they be able to float like it depicts in the commercial?
