The royals sure know how to celebrate the holidays in style!

Princess Beatrice and her sister Princess Eugenie attended The Easter Matins Service at Windsor Castle with their grandmother Queen Elizabeth II on March 31 (without Kate Middleton and Prince William).

Beatrice wore a chic teal wool coat with a matching lace top and feathered hat by milliner Rachel Black. She accessorized with a silver metallic clutch and black gloves.

Not to be outdone, Princess Eugenie wore a cream dress underneath a black coat that accentuated her waist and a fascinator by milliner Sarah Cant. She accessorized with a studded metallic clutch and beige gloves.

Perhaps the sisters get together with Kate Middleton to chat about their fashion secrets?

Not that they need style advice- Beatrice, 24, and Eugenie, 23, are known for their unique flair when it comes to clothes (see Beatrice's floral frock at last year's British Fashion Awards and Eugenie's optical illusion dress at the Paralympics).

And let us never forget the infamous hat that Princess Beatrice wore to the wedding of Kate and Prince William.

See their Easter looks:
