An invitation arrives, and with it a question that sounds simple and never is: what do you wear? A floor-length gown reads like eveningwear for a gala, a summer sundress reads too casual for a ceremony. IsTrendy exists for the middle ground.

Wedding guest and cocktail dresses that are polished enough for the vows, comfortable enough for dinner and dancing, and good enough to wear again the next time an envelope lands on the table. Free U.S. shipping on every order and thirty days to send something back are part of that idea, not a seasonal promotion.
