Brand new Hobbs Rosie Top as seen on Princess of Wales, Catherine (Kate Middleton, Duchess of Cambridge). Size US 12 (UK 16). The blouse is a boat neck and three-quarter-length sleeves with notch detailing. The charming floral print of this shell top will work equally well with denim at weekends as it will under your go-to workwear jacket. ​Princess Catherine wore this on March 22, 2018, while pregnant with Prince Louis. Although she wore it while she was pregnant, the top is not a maternity top.
