I have a black tie dinner in the summer (it's a college thing, so quite lax with the definition of black tie, though). I saw a nice looking dress on eBay, but it's 100% linen. I'm a bit worried that I would just end up looking like a creased dish rag as soon as I sit down. Has anyone worn a formal dress that is pure linen, and do you just end up a creased mess after you've been sitting, or do the creases kind of drop out when you stand? I can't try it on of course so have to take a gamble. It's definitely cut as a formal dress, not a day-dress/sundress, with a low V-neck etc, long, smart looking, and I quite like the colour and style. Just would have expected it to be silk or satin or something mixed with linen. It's not just sitting for the dinner but I'd probably take a bus/taxi to get there to start with, so would be creased before it begins if it's that type of fabric. Or does that kind of dress just look OK with a bit of creasing?!
