Kate Middleton may be a duchess in name, but her reputation precedes her as the queen of Britain's high street.
And once again, Prince William's baby mama-to-be proved her fashion credentials with a pit stop at a London Topshop this week.
An eyewitness tells E! News that the pregnant Kate was, rather fittingly, shopping in the always on-trend maternity department of the Oxford Circus store.
And because the royal is one of the most recognizable women in the world, despite her efforts at keeping the outing low-key, she was still spotted by one of her many adoring and clearly starstruck fans.
"Oh Just an average day," the fellow shopper tweeted. "Kate Middleton smiled at me! :) oh best bit... This was in Topshop! Truly Beautiful :)"
Indeed, the duchess is no stranger to Topshop, and has been a regular customer and wearer of their fashions for years.
Meanwhile, Topshop head honcho Sir Phillip Green spoke to E! News about his most famous customer at the opening of the retail giant's Los Angeles store earlier this month, praising her as a top fashion icon.
"We have a lot of celebs who shop with us," Green said. "We let them shop quietly," he added of his customers' privacy.
Good thing the Twitterati doesn't abide by the same rules.
As for Kate herself, Green said, "I think she's done a fabulous job for England, for U.K. fashion.
"She's leading what she does, she's fabulous. She carries herself very well, it can't be an easy position...but she handles herself very well."
And, of course, with style.
