Never been to one before! The groom's party will be in tailcoats, so it's quite posh. Tips on etiquette, fashion and stuff you've seen in the shops all gratefully received! Shapewise I'm more brick than hourglass (b00bs, slight belly, sturdy shoulders, no waist to speak of). Usually think I look nice/slim then see photos later which disprove that theory! So super-flattering stuff is quite important... and not too much cleavage or leg. Oh, and the cheaper the price, the better. So not too much to ask for, then... Shoppers and fashion gurus of TES, I call on your wisdom!
