New duds for the Duchess!

Like the savvy shopper she is, Duchess Kate took advantage of some end-of-season sales and hit London's Chelsea neighborhood on Monday in search of good deals.

An onlooker tells Us Weekly that the stylish 30-year-old royal, who was dressed in a black knee-length jacket, black tights and suede boots and had her hair styled in a bun, shopped at the store Anonymous by Ross+Bute in the early evening.

After trying on some new pieces from the spring and summer collection, including a pink cardigan and boots, she decided on a marked-down Jewel Collar V-Neck Top — a grey, form-fitting merino lightweight sweater accented with a bejeweled necklace attached along the neckline, that was on sale for 84.50 GBP, $129 USD (from 169 GBP, $259 USD).

While checking out with her only purchase, the Duchess paused and admired a clutch bag, but decided not to buy it in the end. Her visit to the shop lasted about 20 minutes.

"She was really polite, well-spoken and mentioned she would be coming back in the future," the onlooker adds.

The last time the Duchess was photographed out in public was when she walked the red carpet with her husband, Prince William, at the War Horse premiere in London's West End on January 8. Even her 30th birthday, which was the day after, was spent in a low-key manner, when she held an intimate dinner with family and friends within private quarters at one of the properties situated by their home at Kensington Palace.
