Christmas dinner in the context of "Christmas decoration"

A Sunday roast or roast dinner is a British dish traditionally eaten on Sunday. It consists of roast meat, roast or mashed potatoes, and accompaniments such as Yorkshire pudding, gravy and stuffing, and may include condiments such as apple sauce, mint sauce, redcurrant sauce, mustard, cranberry sauce or horseradish sauce. A range of vegetables can be served, such as broccoli, Brussels sprouts, cabbage, carrots, cauliflower, parsnips or peas, which can be boiled, steamed or roasted alongside the meat and potatoes.

The Sunday roast's prominence in British culture is such that in a poll of Britons in 2012 it was ranked second in a list of things people love about Britain. Other names for this meal include Sunday lunch, Sunday dinner, roast dinner and full roast. The meal is often described as a less grand version of a traditional Christmas dinner.

Dinner usually refers to what is in many Western cultures the biggest and most formal meal of the day. Historically, the largest meal used to be eaten around midday, and called dinner. Especially among the elite, it gradually migrated to later in the day over the 16th to 19th centuries. The word has different meanings depending on culture, and may mean a meal of any size eaten at any time of day. In particular, it is still sometimes used for a meal at noon or in the early afternoon on special occasions, such as a Christmas dinner. In hot climates, the main meal is more likely to be eaten in the evening, after the temperature has fallen.

A party hat is any of a number of celebratory hats, most typically in the form of a conical hat made with a piece of thin paperboard, usually with designs printed on the outside and a long string of elastic acting like a chinstrap, going from one side of the cone's bottom to another to secure the cone to the person's head. Party hats are worn most often at birthday parties, especially by the guest of honor or at New Year's Eve celebrations. In the United Kingdom the hat is made of paper and is in the shape of a crown, and is most typically worn during a Christmas dinner. The hat is generally received from a Christmas cracker cracked with someone near oneself at the dinner table. The party hat has its origins in the dunce cap or sanbenito worn by misbehaving or poorly performing schoolchildren from the mid-19th century to the early 20th century, with its festive decoration and society's positive attitude toward the wearer indicating a relaxation, or even reversal, of certain social norms.

Non-conical hats worn to signify an occasion's informal and festive status include decorated top hats, hats made from balloons, and Mickey Mouse ears. The beer hat or "beer helmet", patented by Steve Nelson in 1985, is another form of party hat in which cans of beer are attached to a rigid hat with a straw leading from the cans to the wearer.
