There’s no denying that the best dresses always come out to play in autumn/winter. With, dare we say it, party season only a couple of months away, we’re already starting to see excellent frock options hand in new-in sections. In other words, you’re more likely to find a wedding guest dress that’s really special—one you’ll be really excited to wear—once the likes of linen and cotton are ushered out in favour of satin, velvet and sequins. From high-shine to embellishment, the dresses currently on offer are as tasty as the treats you’ll find in a box of Quality Street chocolates—and the colour palette isn’t too dissimilar, either. So what makes for a great autumnal wedding guest dress? Really, it’s down to two things: silhouette and styling.
