Adios, G-strings.

Retailers are hailing the return of "big knickers" -- and "Mad Men" may be responsible (in case your boyfriend needs someone to blame), the Daily Mail reports.

The retro lingerie worn by the likes of Christina Hendricks has inspired a new demand for high-waist panties, according to the paper.

A recent survey reportedly found that sales of large panties have risen by 42 percent in just three months, while Figleaves has seen a 28 percent increase, and Rigby & Peller (which made Bridget Jones' infamous "big pants") has had a 15 percent increase.

Both retailers tell the Daily Mail that they are selling roughly two pairs of fuller briefs for every thong.

"This season big is definitely beautiful," Rigby & Peller creative director Nicky Clayton tells the paper. "They are sexy as well as comfortable.

"There is now more detailing: lace, ruffles and accessories that accentuate rather than just cover up what can be a lady's best asset. It's been championed by the underwear-as-outerwear look.

"Women want glamour as well as comfort now and G-strings are definitely being squeezed out by this trend."

"We have seen a big shift away from the skimpier shapes," adds a Marks & Spencer spokeswoman.

"Gone are the days of the off-white Bridget-Jones-style knickers."

Thank goodness for that. Now, who's going to break the news to poor Sisqo?
