A pin-up model (known as a pin-up girl for a female and less commonly male pin-up for a male) is a model whose mass-produced pictures see wide appeal as popular culture. Pin-ups are intended for informal display, i.e. meant to be "pinned-up" on a wall. Pin-up models may be glamour models, fashion models, or actors. These pictures are also sometimes known as cheesecake photos.[a] Cheesecake was an American slang word, that was considered a publicly acceptable term for seminude women because pin-up was considered taboo in the early twentieth century.[1]

The term pin-up may refer to drawings, paintings, and other illustrations as well as photographs (see the list of pin-up artists). The term was first attested to in English in 1941;[2] however, the practice is documented back at least to the 1890s. Pin-up images could be cut out of magazines or newspapers, or on a postcard or lithograph. Such pictures often appear on walls, desks, or calendars. Posters of pin-ups were mass-produced, and became popular from the mid-20th century.
From Veronica Lake and Marilyn Monroe in the 1940’s and 1950’s to Dita von Teese today, pin-up girls have been displayed on walls and billboards for generations and admired by men and women alike. No matter their dress size, pin-up girls wear clothes that accentuate their assets, bring out their sexual appeal, and make them look gorgeous, fun, and elegant at the same time. To start channeling your inner pin-up girl, you must balance style with natural beauty, grace, and confidence.
Read my article Sammy Davis, for complete details, but no fashion designer had more influence on the 1950s fashion than Christian Dior. His influence can be seen in the A-line dress that he introduced in the spring of 1955. Until that point, women had worn fashions with tightly nipped-in waist and broad shoulders. The A-line was seen as radical because of its narrow shoulders, elongated waistline and trumpet-like flared hemline. Take a look at this vintage A-line dress from Rose Wholesale (@rosewholesale_official) to create this look for yourself.
