But glow-in-the-dark underwear? Australia-based company LuminoGlow could be on to something.
The brand has created a new line, Aurora, using white Italian lace that glows green when the lights are dimmed - but that's not all.
According to LuminoGlow's blog, the glowing lace has been strategically placed on each garment to "accentuate your body in the right areas." Clever.
So, how does it work? As Elite Daily reports, there's some admin involved.
The wearer must hold the lingerie up near a bright lamp for a few minutes before putting it on. Then, once the lights are turned off, the glow effect will last for around 10 minutes - just enough time to surprise your partner.
Clearly, the range has already been a hit. Jan Hawley, who founded the brand in 2008, says fans love her concept because it "indulges their senses and the glow in the dark quality is sheer delight."
