As a child my mother would smear Vaseline on my face and arms then apply the glitter, the Vaseline base ensuring that the glitter stuck and stayed on. Nowadays Vaseline and glitter equals a very bad sunburn, so I have taken to using glitter spray.
The glitter spray comes out in a fine mist and leaves your body, or hair, with a nice shimmery glow. I buy my Jerome Russell spray at Wonderful World in Trinidad for around $35.00, it is the one pictured below in the red can. One can is finished by the time I spray both myself and a friend on the arms, back and stomach. It does not last all day as the coarser, traditional glitter, but both of them rub off anyway with sweat and rubbing against other people.
Other sprays by Jerome Russell are also available, though a bit more expensive than the one in the red can; the Punk Spray sells for $45.00TT and the Bwild for $50.00TT. I have found online prices are comparable at around $7.00US.
