Ladies, this is the first wedding I've attended since I was a flower girl! Need some fashion advice. Small (less than 30 people) Spring wedding in Vegas. Evening reception dinner at a restaurant and partying on the town after. Indoor ceremony at a very nice casino chapel. My husband is best man. The invite has noted "formal" which I find to be the most vague attire note on the planet, especially in Vegas. I'm lost as to what would be appropriate for both the wedding and a night on the town. And formal and Spring clash in my head. I picture light and bright colors and floaty short dresses for a Spring wedding, but all things I've seen on formal dressing suggest subdued colors and long dresses. I'm afraid either looking too glitzy or too dowdy. Would sequins be alright? Am I stuck with dark and neutral colors?
