Things You'll Need
Bra or swimsuit top
Hot glue and glue sticks
Sea-toned eye shadow and glitter
Use sea-tone eye shadow and sea-tone glitter on face, shoulders and arms. Coordinate the color of top with material used for bottom. Other possible accessories could include a golden comb (in legends mermaids used them to comb their hair), and a "pet" stuffed octopus or starfish. In lieu of the fantasy hair, the person's own hair can be highlighted with blue or green spray-on hair coloring popular at Halloween.
