When’s the best time to buy underwear? Now, of course. The best deals you’ll see all year are happening during Cyber Monday and throughout the holiday shopping season. It’s the perfect time to start throwing out your old panties and starting over with some celebrity-approved skivvies.

If you’ve ever wondering how stars avoid wardrobe malfunctions in those see-through dress, nine times out of ten they are wearing undetectable underwear from Commando. That was Ciara’s secret at the Billboard Music Awards. The brand’s offering $50 off of purchases of $200 or more when you use the promo code ASKFORMORE, so you could stock up for yourself and a friend.

If you’re on the hunt for a comfortable bra, Cosabella has been a celebrity and InStyle editor’s favorite for years. Stars that have worn Coasabella include Gwyneth Paltrow and Jennifer Lopez. Now you can add your name to the list, thanks to the epic sale at Saks Fifth Avenue.

Last but certainly not least are the ultra-comfortable thongs by Hanky Panky. There’s nothing worse than an ill-fitting thong. But Hanky Panky’s, which go up to a size 3x, don’t ride up like your typical thongs. That’s probably why Kim Kardashian has admitted that she’s a fan. Right now, Hanky Panky styles are up to 65 percent off.

So what are you waiting for? Treat yourself to some quality and affordable undies before Cyber Monday’s over.
