With spring officially around the corner, wedding season is firmly on the horizon - and if your diary is filling up with 'I dos', now is the time to start planning what to wear.

New-season collections have already landed, bringing a host of stunning occasionwear pieces perfect for ceremonies, receptions and everything in between.

And if you're looking for inspiration, I've turned to the Princess of Wales's favourite high street brands for polished yet accessible event dressing.

Think elegant midi and maxi silhouettes - shapes that Kate typically favours - alongside timeless polka dots, satin finishes, delicate lace and romantic florals.

Colour is key this season if you want to stand out in the sea of guests. A vibrant fuchsia frock from Boden instantly caught my eye - it's bold, joyful and exactly the sort of statement shade that feels right for a sunny celebration. 

On the other end of the spectrum, if you prefer something more classic and understated, Hobbs' navy floral style 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 and sleek satin styles, these are the new-season dresses I'm bookmarking for wedding guest season - and I suspect the Princess of Wales would approve too.
