Kate Middleton just wore her favorite winter outfit AGAIN and looked so classy

Kate Middleton stepped out again in what is no doubt a firm favorite outfit for her, having worn it on multiple public outings in the past. 

• One of Kate Middleton's favorite outfits was seen once again today when she made her latest public appearance with Prince Charles and Duchess Camilla. 
• The Duchess of Cambridge recycled her gray, belted Catherine Walker coat and paired it with black tights and black heels as usual. 
• This royal news comes after the BIZARRE detail about photos of Kate you've probably never noticed was pointed out. 

Kate, who primarily resides at Kensington Palace with Prince William and the Cambridge kids, joined her father-in-law Charles and the Duchess of Cornwall for a royal working day in London today, with the three of them making a rare appearance as a trio. 

The future King and will-be Queen Consorts were out to visit The Prince's Foundation training site for arts and culture at Trinity Buoy Wharf, with Kate opting for a seriously classy coat we've seen her in before. 

The Duchess, who got super hands-on during a very different type of royal work day this week, chose the gray, belted Catherine Walker coat dress with a black collar, tights and black heels combination that she previously rocked in both 2020 and 2019. 

The coat features a figure-hugging belt around the waist, complete with a black buckle that match the delicate black buttons on the cuffs. 

Kate wore an almost identical look when she and the Queen appeared on a joint visit to King's College in London in March three years ago, acessorizing with a simple black fascinator as she smiled and walked alongside the monarch, who chose a brighter, pastel pink ensemble. 

Then in January of 2020, Kate chose the chic, waist-cinching winter piece once again when she and her husband, Prince William, went to work together for Holocaust Memorial Day. 

The mom-of-three once again teamed the regal yet understated coat with a subtle, small handbag and her go-to black tights and shoes match.

With Kate having access to all the high-end clothes she could ever need and being styled by the best royal dressers, it's fairly rare that she publicly wears an outfit more than once or twice—so it's safe to say this one is certainly one of her favorites when it comes to chilly days.
