Let's get straight to it — here's what actually matters on this one.

• Choose breathable formal fabrics (lightweight wool blends or fine cotton) for daytime events, saving heavier fabrics for evening functions.
• A well-fitted outfit matters more in wedding season than any other time — you're standing, greeting, and moving for hours in warm, crowded venues.
• Avoid overly tight formalwear for long events; a half-size looser fit with good tailoring is far more comfortable than a snug 'photo-ready' fit worn all day.
• Layer-light where possible — a well-cut single layer beats a heavy blazer worn purely for formality in a warm venue.

The fit-and-fabric-health takeaway: Long wedding events are the ultimate stress test for fit and fabric — comfort issues that are minor for an hour become significant over six.
