Leicester City F.C. Logo

The club's home colours of royal blue shirts, white shorts, and royal blue socks have been used for the team's kits throughout most of its history. The first sponsorship logo to appear on a Leicester shirt was that of Ind Coope in 1983. British snack food manufacturer Walkers Crisps held a long association with the club, sponsoring them from 1987 to 2001.

The club have three main nicknames – The Foxes, The Blues and City. 'The Foxes' is the most common nickname for the club, whereas 'The Blues' and 'City' are local terms, usually used by the supporters. Other names include 'The Filberts' and 'The Fossils.' An image of a fox was first incorporated into the club crest in 1948, as Leicestershire is known for foxes and fox hunting. This is the origin of the nickname "The Foxes".

The club mascot is a character called "Filbert Fox". There are also secondary characters "Vickie Vixen" and "Cousin Dennis". The current shirt badge has been used since 1992 and features a fox's head overlaid onto a Cinquefoil, the Cinquefoil is similar to the one used on the coat of arms of Leicester. In the 2009–10 season which was the 125th anniversary the home kit featured no sponsor and a new central crest with "125 Years" below. The crest was slightly changed, this change included the fox in the crest to have a white area under its nose. The circles in the crest were also moved around.

In 1941, the club adopted the playing of the Post Horn Galop prior to home matches. It was played over the PA system as the teams came out of the tunnel at all home games. The club since replaced it with a modern version, which is now played as teams emerge for the second half. For the first half, the post horn has been played live on pitch by Paul Hing since 2009. 'Foxes Never Quit' is the club's motto, which is placed above the tunnel entrance as the teams head out onto the pitch.

8 July 2016 saw the club launch their new 3rd away kit for the 2016-17 Premier League season. It will feature in their 2016-17 UEFA Champions League campaign, and will also be in use for Leicester's debut match in the competition. The design took inspiration from the 1983/84 kit, and boasts a clean white design with thin blue pinstripes on the shirt, as well as a textured form stripe design across both the shirt and shorts.
