Duchess Kate Buys $55 Maternity Dress From Topshop

Kate Middleton is Lovestruck -- by a dress! The pregnant Duchess of Cambridge did a little maternity shopping this week at a London TopShop, where she picked up a sweet flowered frock by U.K.-based clothing concession Lovestruck, a rep for the company confirms exclusively to Us Weekly.

Middleton, 31, who is expecting her first child with Prince William in July of this year, purchased the brand's Deirdre dress, a delicate spring sheath with a mandarin collar, a cross-over neckline, and a elasticized waist -- to accommodate the first-time mom-to-be's growing baby bump! The price tag for such stylish garb? A very affordable 37 pounds, or $55.

"It's so exciting that the Duchess of Cambridge bought one of my designs," Lovestruck designer Erika Shaw tells Us. "I think it's great that Kate wears high street brands."

No doubt other expectant moms will be taking a fashion cue from the pregnant royal and rushing out to pick up the feminine frock. Middleton has become something of a style icon since stealing Prince William's heart -- after the couple announced their 2010 engagement with an official photo of Middleton in a blue Issa wrap dress, copycats ran to get their hands on the gorgeous sheath. It sold out within 24 hours.
