Erin Mullaney, Buying Director at Browns, does just that and confesses that she finds packing for nearly five weeks a 'daunting task'.

Especially what keeps her looking awake through the numerous shows and after-show parties, even when she doesn't feel it.

"There are a few secret beauty weapons that I always take with me to hide my tiredness and keep me looking fresh.

Radiance Plus Self Tanning Cream-Gel, £25.50 by Clarins gives my skin a healthy glow.
