What to Wear to a Wedding Guest: Teens

Wedding guest attire for teens follows the same semi-formal dress code as adults—cocktail dresses or suits with ties—but proportions matter when you're still growing or between standard sizing. Look for structured pieces that fit your current frame rather than oversized styles, since semi-formal demands a polished silhouette whether you're in a sheath dress or a tailored blazer. Hem lengths and sleeve proportions should be adjusted to your actual measurements to avoid looking like you're borrowing from an older sibling's closet.
