A magenta frock from Ro&Zo instantly caught my eye - it's bold, joyful and exactly the sort of statement shade that feels right for a sunny celebration. Meanwhile, Farm Rio's Rococo Flowers midi dress brings to mind a style Kate once wore during her royal tour of the Caribbean, making it perfect for channelling a vibrant tropical mood.On the other end of the spectrum, if you prefer something more classic and understated, Hobbs' mint green floral dress will never look out of place at a wedding.What I love about these high street finds is how wearable they are beyond the big day. Many of the dresses could easily be styled again for garden parties, summer events or even dressed down with flats for a more relaxed look.From floaty floral maxis to chic polka dot midis, these are the new-season dresses I'm bookmarking for wedding season - and I suspect the Princess of Wales would approve too.
