Answer;

A black T-shirt

Explanation;Materials can be either reflectors and absorbers of waves such as light waves, sound waves etc. Reflectors are those materials that reflects waves, such that the waves bounces back on hitting the surface of those materials.Examples of such materials are those with smooth and shiny surfaces, while those with rough and opaque surfaces are poor reflectors of light. Additionally, these materials that are good reflectors are poor absorbers while those that are poor reflectors are good absorbers of light. Dull surfaces are the best emitters and absorbers of light but the worst reflectors of light waves. White surfaces or polished surfaces are bad and worst emitters and absorbers of light waves respectively
