Welsh fashion designer Robyn Coles took that advice to heart when choosing how catwalk models should show off her new range of headgear.
The models appeared at the White Rabbit Studio in Shoreditch, east London, in a naked procession that included actor and comedian Jeff Leach.
Coles's friend and former Miss Wales Sophia Cahill helped out by joining in too, despite being eight months pregnant.
"Today, me n my baby strutted that catwalk head held high, no man was holding my hand.... #singlepregnantwomen," she later said on Twitter.
She had previously promised: "I will be walking down that catwalk head held high! Middle finger held even higher!"
By contrast, comedian-turned-male-model-for-the-day Jeff Leach quipped: "Hope seeing me nude in The Metro this morning doesn't put you off your muesli!
"Having said that, crime in the city is down 14% this morning!"
