PRHOT STUFF: Dusky pink bra £20, matching briefs £12, Next (L) and grey body £19.99, Topshop
But just because you want to keep snug on the inside, it doesn’t mean to have to compromise on style.
Our fashion experts prove you can wrap up warm in thermals under your clothes and still stay sexy.
Here our model Issy shows off her cosy underwear and ways to beat the big freeze.
Celebrity stylist Marie McCaver says: “Keeping warm and layering up doesn’t have to be at the expense of style.
PRWEATHER WARMING: Black body £8 from Primark
“The high street is full of snug and warming undies”Marie McCaver
“Some of these winter warmers might be for you – or your partner’s – eyes only. But they will help you feel sexy when you’re wrapped up and facing the big chill outside.
“The high street is full of snug and warming undies which will keep the cold out and the heat in. Whether it’s a slip or a set or a body suit under your clothes the trick is to layer things up.
“And your base layer – the one closest to your body – is always the most important. But that doesn’t mean it can’t look great as well as being functional.

PRIT’S SLIPPY OUT: Cream slip £12.99 from TK Maxx
“This season I am loving the return of the slip to smooth out your silhouette, some legwarmers and chunky socks and leg warmers, as well as pale pastels that are so on trend and look stylish next to your bare skin.
“And when all else fails, a chunky cardigan or snood on top of something a bit slinky will always be in fashion.
“Cotton and thicker materials will always work harder for you, as will anything with detailing. Just remember to check with each store that it’s faux – not real – fur trim on any item you buy.”
