We welcome all formalwear. Choose whatever makes you feel comfortable and gorgeous--blazers, dress pants, skirts, dresses, heels, flats, ties, tiaras, whatever. Ladies, don't feel obligated to wear dresses. Gentlemen, you are welcome to wear skirts, as long as they are wedding-appropriate. Hey, it's the 90s.
But we're going to look pretty phenomenal, so you should, too.
