Me, too 🤗 It's one of those dresses that many might say you can get for £80 at a high-street chain, but you can even tell from the photo that this one's just better. I don't always think price reflects quality; it often just reflects ambition. I'm willing to bet, though, that if a twin wore this alongside her sister in a knock-off, you'd immediately know which was in the Balmain.
Glad you seem to have found a "really you" dress, though! Your event sounds fun. Enjoy it!
