It's no secret the Made In Chelsea star has a thing for fashion - she has her own style blog and is regularly seen on the FROW at London Fashion Week - so it was really about time she created her own line!
The pretty brunette made sure she was looking picture-perfect for her big day, sporting a pink and blue floral two-piece covered in a checked pattern.
Her chic co-ords featured a sleeveless top with a peplum hem, while her matching pencil skirt was both girly and elegant with its below-the-knee hemline and figure-hugging design.
Rosie added a touch of luxe designer to her outfit by sporting her favourite studded Valentino heels, accessorising with a gold watch and a few dainty rings.
And Chelsea gal Rosie has told us in the past she always likes to have polished nails, so for this occasion she slicked her pointers an immaculate pale pink hue.
Her hair was gorgeous too - after an early morning visit to Duck & Dry salon in Chelsea, Rosie emerged with her light brown tresses styled in a beautiful braided updo.
Clearly chuffed with her fancy barnet, the starlet tweeted a quick pic along with the caption: "Thank you @duckanddry @SnowdenHillHair for the perfect plait for my super exciting day today. You guys are the dream!"
Loving the look, Rosie!
