What to wear at your Engagement Party Wedding Planning He popped the question, you said yes and now you're celebrating the fab news at an evening soirÃ©e with your nearest and dearest. So the burning question is...what to wear at your engagement party?If it's an evening do, I'd definitely go for something dark, figure-hugging and elegant; after all, you've taken a pretty grown-up step getting engaged, so why not go the whole hog and wear a grown-up outfit? And steer clear of anything remotely bridal - the time will come for that!I love this Perseus dress (left) from Monsoon (Perseus was the brother of Helen of Troy, who was so beautiful that her face famously launched a thousand ships after she eloped/was kidnapped by Paris, thus beginning the Trojan War).And I think that if you wore this dress, you really would feel and look incredibly beautiful and quite the radiant bride-to-be.A less structured but equally as beguiling dress from Phase Eight is this Prima Rosa Maxi Dress (below), perfect to wear as you sip your champagne and circulate round the room, excitedly talking to everyone about your plans for the forthcoming nuptials. Alternatively you could opt for the understated beauty of this stunning full-length Dessy gown Style 6741 (left) with cut-away sides revealing a silver metallic bodice. The close-up is featured at the top of the page which enables you to see quite how alluring it is. You don't have to wear long, of course. This high-lo dress (below) from Dessy is superbly glamorous, with its black fleur embroidery overlay, 3/4 length sleeves and deep V back. The modified circle skirt gives a glorious sweep as you turn and you'll feel the absolute Belle of the Ball.The floral jacquard Verdure Tapestry Dress from Hobbs (below) is the height of sophistication and is a perfect example of what to wear at your engagement party; simply cut, colourful without being garish, and classy - what more could you - or your fiancÃ© - ask for?
