Daisy previously attended her step-sister Phoebe’s wedding

Phoebe chose an intimate wedding with just immediate friends and family on the guest list. The Prince and Princess of Wales did not attend, so it’s not known whether they would attend Daisy’s nuptials.

Daisy previously discussed her “androgynous and timeless” style with HELLO!, giving a glimpse into what her wedding look might look like. She said: “I am a big believer in simple but elevated basics to build a small but mighty wardrobe.” She also said she tries to “avoid anything that is too trend-driven”.
