5 Elegant Outfit Ideas for September Weddings

September is one of the most popular months for weddings – warm golden light, late-summer vibes and the first hint of autumn in the air. But it also brings a big style dilemma: what do you wear to a wedding when it’s no longer summer-hot, but not yet winter-cold?

The answer: elegant dresses that balance sophistication, comfort and season-appropriate fabrics. Here are 5 Isadora London styles that will make you the best-dressed guest this September.

1. Chic Slit Maxi Dress
