This Cinq a Sept dress is the perfect LBD for a wedding or cocktail party or pretty much any event you have this fall. It’s versatile, sexy yet elegant, and on-trend without being so trendy that it’ll be out next year. The only thing is you’ll definitely want your Spanx for this one. While I typically try to snag fancier dresses for weddings and special occasions on sale (since you only wear once or twice ever), this one is definitely worth investing in, because you’ll wear it for years and it’ll always get compliments. You could honestly wear it to two weddings in a row, with the same group of peeps, switch up your accessories and be good to go.
