Love Princess Charlotte’s 9th Birthday Photo 🎂. Wondering who designed her cute outfit? Mystery solved! Princess Charlotte is wearing the French brand Cyrillus Paris. Charlotte wore a beautiful Girls Red Cotton Cashmere Blend Sweater, Girls Navy Blue Cardigan Sweater with a Liberty London Floral print collar, and Girls Dark Blue Denim Button Down Skirt. Thanks 🙏 @foundbybojana for the outfit info. Image Source: Prince and Princess of Wales / Instagram.
