Kate Middleton isn't the only royal to have a style crush on Jenny Packham.
Country pop royalty Taylor Swift discovered her love for the UK-based fashion designer when she wore a deep teal Packham cocktail dress at the BBC Radio 1 Teen Awards in London on Sunday.
The 24-year-old was in a festive mood in the boatneck number which featured gold and red embellishments which resembled Christmas decorations. (Psst, Taylor! Isn't it a bit early to be wearing your holiday best?)
Harry Styles' ex continued the holiday trend by wearing gold beaded Christian Louboutin sandals and elegant Neil Lane earrings.
But Tay Tay isn't the only celeb who rocks out in the Duchess of Cambridge's go-to designer; other Brit sensation Kate Winslet, who is pregnant with her third child, sported a red low-cut Jenny Packham at the "Labor Day" premiere in October.
Middleton wore Packham while she was pregnant with Prince George and sent tons of Kate style watchers running to get out their credit cards when she wore a cute polka dot Packham frock when she presented the heir to the throne the day after she gave birth.
Most recently, the first-time mum wore a stunning floor-length Packham at the 100 Women In Hedge Funds Gala.
Who do you think rocks Jenny Packham better: Taylor or Kate?
