It's Royal Ascot week, and various members of the royal family will turn out in their finest and fanciest attire, but what are the clothing dos and don'ts when it comes to the highlight of the social calendar? And how about the rest of the jam-packed royal year — Polo: hat or no hat? A diplomatic reception: white tie or black tie? And since when were fascinators a no-no? From sporting events to church services and celebrations to commemorations, dressing for the royal year could be a potential minefield. Here's a breakdown of suitable attire for each event.

Royal Ascot — June

There is a VERY extensive list of rules, but basically it's:

Women: Formal daywear, which means dresses and skirts of "modest length" (just above the knee or longer), and straps on dresses should be at least an inch wide. Fascinators are no longer allowed as headpieces need to have a base of four inches or more. No off-the-shoulder or halter tops, and ladies are advised to wear wedges over stilettos so they do not sink heel-first into the ground.
Men: Black or gray morning dress, which means a tailcoat and waistcoat with matching trousers, along with a dress shirt and tie. No cravats. Black or gray top hat and black shoes.

Polo (Behind the Scenes) — Summer

Women: Just because there are horses involved, there's no posh dress code behind the scenes. It's your basic "running errands" attire — jeans, tees, and flats.
Men: Although Prince Charles maintains an element of formality, the younger men stick with jeans or shorts with a t-shirt or polo shirt. As long as nothing is torn or stained, the more casual the better.

Weddings — Mainly Summer

Women: The rules are slightly more relaxed on the "daytime formal" dress code. Fascinators are OK, as are shorter hemlines.
Men: It's still very formal for the fellas, though, with a morning suit dress code.

Wimbledon — July

Women: There's no formal dress code for general ticket-holders, but a smart-casual dress is usually the way to go. The general rules are "not too short and not too tight." Lots of ladies favor white or cream.
Men: No formal dress code for general ticket-holders, but torn jeans, running vests, dirty trainers, and sports shorts are not allowed. In the members area, the dress code is more defined, with men required to wear a lounge suit or tailored jacket, shirt, tie, trousers, and dress shoes.
