You could study style for years, and still have scope to learn more. It’s an interesting topic that doesn’t always get the love it deserves, with some dismissing it as frivolous. We wear clothes everyday (although a duvet day now and then is compulsory), and wearing something you love can often change your mood. In homage to the dynasty that is style, this A-Z guide will bring you a little insider information on one of our favourite subjects, this week concentrating on all things G. Gucci The story of Gucci began in a little shop in Florence in 1921. Luggage was at the center of Guccio Gucci's vision for the company and it became a family affair when his son Aldo started working with him. Aldo is responsible for creating the interlocking double G logo, inspired by his father's initials. Rodolfo, another of Guccio's sons was a talented designer, creating the Flora print scarf worn by Princess Grace of Monaco, with the help of painter Vittorio Accornero. Gucci was launched in America in 1952, and the rest as the saying goes, is history. GQ Magazine A publication that dresses beautiful men in suits and puts them on the front cover is likely to enjoy a certain amount of success and this definitely rings true for GQ magazine (or Gentleman's Quarterly). It was originally launched under the name Apparel Arts in 1931. It was re-branded in 1967 as GQ and in 1983, GQ was bought by global publishers Condé Nast, marking a change in direction. Editor Art Cooper ensured there was a broad range of subjects included in each issue, establishing it as the number one publication for men. Givenchy In 1952, Hubert de Givenchy burst onto the fashion scene with what Vogue would later call a "stunning debut collection". 1954 saw Audrey Hepburn wear Givenchy in the film Sabrina and this marked the birth of the Sabrina neckline. The designer was known for speaking out against what he called a "fashion dictatorship" where fashion editors only promoted a handful of looks, limiting women's clothing choices. Audrey Hepburn wore Givenchy a number of times, becoming somewhat of an ambassador for the brand and Jacqueline Kennedy was also pictured in Hubert's designs. GAP GAP is an American multinational clothing and accessories retailer. It includes five divisons, GAP or Gap Inc, Banana Republic, Old Navy, Piperlime and Athleta. Founded in 1953 by Donald G. Fisher and Doris F. Fisher, the Fisher family still participate in the running of the company. Doris and Donald's son is the current chairman and he also sits on the board of directors as does Doris. Donald passed away in 2009. The current CEO is Glenn K Murphy and it has 3,064 stores worldwide and counting.
