Beauty buy: Sunjunkie sunless bodymist
It's a spray that can be used at a 360 degree angle so you can get to all those awkward bits without any dangerous gymnastics, for a professional airbrush finish.
We wouldn't recommend it for a full tanning job, but rather to keep an existing fake tan radiant for as long as possible, or to smooth over any parts of your tan that are fading.
Who needs sunshine to be a bronzed beauty eh?
