It's official - we’re right on the cusp of the social season, and alongside the likes of Ascot and Wimbledon (and the very specific dressing they require), it also signals the start of wedding season.
I love a wedding as much as the next person. But now that I’m in the midst of planning my own for 2027, I think my appreciation for both being invited and everything that unfolds across a wedding weekend has multiplied significantly. I'm enjoying being a guest who simply turns up, cries with happiness, dances and drinks champagne more than I ever did before.
I’ve got a very chic run of weddings lined up for 2026: one in the Cotswolds, one in Provence, and one on the sunny island of Mallorca - all with entirely different dress codes. Think South of France chic, black tie, and a slightly overwhelming but freeing “whatever you like”, which really means I’ve been deep in various tabs trying to decode what each one actually requires.
And while summer weddings tend to conjure up images of floaty florals and pastel palettes, I’m here to say: don’t write off darker hues. A rich chocolate, elegant navy, or deep red can feel just as appropriate in the sunshine when done right, and they're also appropriate for events all year round. For summer, pair with lighter white, nude, gold or silver accessories.
Wedding guest shopping, however, can feel like a bit of a minefield - especially when you’re trying to keep things within a reasonable budget. So, I’ve done the legwork and scoured the internet for the best pieces I could find for under £300. I’m fully aware that £300 is still no small spend on a dress, so the aim here is pieces that feel special enough for a wedding, but versatile enough to re-wear for other occasions (because cost per wear is everything).
I’ll be updating this throughout the season, so keep checking back for new finds and fresh inspiration - whether you’re heading to a countryside ceremony, a beachside “I do”, or something a little more black-tie.
