Kate Middleton may recycle her classic ensembles [1] once or twice, but she does so [2] on the most appropriate occasions. While the last time she wore this peplum-finished L.K.Bennett suit was during Queen Elizabeth II's Diamond Jubilee tour in 2012, Kate's look got a fresh update for ICAP's charity day [3].

Rather than contrasting her teal separates with black accessories — like a fascinator and thick belt — Kate went for monochrome shades, highlighting the jewel tone of her suit. It is, after all, a fitting, almost "Christmasy" color for the holiday season [4].

Read on to see how functional Kate's outfit was [5] as she happily made calls, showed off her sapphire engagement ring all the while, and even took on a game of ping-pong! Then shop for the duchess's practical pieces, so you can make power moves during the most wonderful time of year, too.
