We’ve checked “yes,” marked our calendar, and even secured a date. But when it comes to the outfit, we’re paralyzed. Here, three dresses that answer the age-old question, “what should I wear?”

A WINERY WEDDING
The short length and light hues dress down the ruffles and beading, making it the perfect amount of polish for a wedding guest.

A FIRST DATE
This frock nails our 3F test (flirty, fun, and flattering) making it perfect for first, second, and third dates.

A COCKTAIL PARTY
This longsleeve mini shows off the gams but still keeps us covered, making it the perfect LBD for winter cocktail parties.

Our Rue Picks: 45 Dresses For Every RSVP Boutique opens today, Thursday October 6, 2011.
