I have a theory. On BBC’s So You Think You Can Dance, the contestants’ main challenge isn’t the samba or jazz, it’s trying to outshine presenter Cat Deeley’s legs. I have always admired how long and svelte they are, but seriously, have you seen the shine she’s got going on these days? She could guide ships to shore with those pins. If you’re planning to flash a bit of leg on an evening out, a make-up artist once told me a great trick to make legs look more slender: hair serum. Yep, rub a little along your shins and it will reflect the light. Alternatively, try blending a highlighter that you would normally use to amplify your cheekbones. Show me to the dance floor, cha, cha, cha.
