Though unmentionables once referred to all manner of things––Grandpa's missing hands, Phlogiston theory, and the truth about cats and dogs—only one thing is worth not mentioning today. Don't say a word with today's romance-clad Groupon: for $39, you get $100 worth of designer intimate apparel for men and women at Di Moda European Lingerie.

Di Moda European Lingerie's intimate apparel saunters in from across Europe to swathe male and female silhouettes in high-quality fabrics and flattering cuts. Lace-laden bras ($53.95+) flirtatiously festoon curves; seamless bras ($39.95+) ensure a smooth, line-free fit. Shoppers can also trim waistlines to facilitate swan dives through closing subway doors with an embroidered bodysuit ($139.95) and myriad other [control panties] (http://www.dimodalingerie.com/Panties/Category/Control_Panties.html) ($27.95+). An Italian lace thong ($52.95) forgoes elastic to hug hips with soft mesh, and Italian satin pyjamas ($97.95), like counting pole-dancing sheep, add sultry moves to bedtime. Men can replenish dresser drawers with cotton briefs and boxer briefs ($19.95+) or hibernate inside a set of navy blue 100% cotton PJs ($129.95).

Though Di Moda European sometimes features a discounted price online, this Groupon still offers the best deal available.
