The week's best royal style: Princess Mary, Queen Mathilde, Princess Eugenie

Luxurious gowns and sparkling tiaras were in order as much of the royal style moments this week can from Queen Margrethe 's 75th birthday party in Copenhagen. Princess Mary of Denmark dazzled as she arrived for a dinner at Christiansborg Palace. The elegant royal chose a stunning pale pink Birgit Hallstein gown pairing it with small earrings, bracelet, hair clips and, of course, a large diamond tiara.

Princess Marie of Denmark also turned heads as she arrived for the same event in a navy lace peplum gown pairing it with her Diamond Floral Tiara and brooch from Queen Alexandrine as a pendant. Queen Mathilde of Belgium arrived in style wearing a fuchsia pink silk Armani Privé gown and her own royal crown. Her Nine Provinces Tiara made its full debut at the event after wearing the bandeau version in the past.

The guest-of-honor though, Margrethe arrived wearing a stunning bright red gown complete with floral applique across the torso, a simple pearl necklace and her Floral Aigrette Tiara along with pieces of the ruby, diamond and pearl set from the crown jewels.

Away from the birthday celebrations, the always-fashionable Zara Tindall stunned in a chic navy blue quilted coat. She paired the outfit with nude heels, a cream hat and bag for a fun day out at the Crabbie's Grand National 2015 Day at the Aintree Racecourse with husband Mike.
