Pin-up fashion is synonymous to and a combination of Burlesque, Rockabilly and Old Hollywood Glamour in terms of clothes, hair, makeup, shoes and accessories. It's all about being classy yet elegant, flirty without going overboard. It's more on minimalism and simplicity with just a little skin exposure. With a little cleavage men are teased. This style celebrates women, from their curves to their flawless faces. Don't worry if you think you aren't skinny enough to pull off the perfect pin up girl look. The pin-up  culture embraces your natural hips and curves. 
Pinup Girl Clothing: Leaning a little more mainstream and rockabilly, Pinup Girl has an enormous fanbase that spans a variety of subcultures and demographics, from hardcore pinup enthusiasts to true vintage hounds to Disney fanatics. The shop always features some kind of sale and carries collections inspired by everyone from Audrey Hepburn to Dita Von Teese that go up to a size 4X.
To get pin curls: dab gel onto the root of a small section of damp hair, then twirl that section of hair around your finger until you get to your scalp. (You can twirl in whatever direction you’d like the curls to flow.) Slide your finger out of the curl and pin the curl to your head. Repeat for your entire head of hair, allow hair to dry, then remove pins, and voila![1]
^{Vixen by Micheline Pitt: Micheline Pitt’s pinup empire includes Vixen, La Femme Noir, and Bad Girl Denim. The latter is a line of retro-cut jeans and shorts popular among bloggers. La Femme Noir leans goth, with a lot of lace, coffin accessories, and body-hugging, well, everything. But Vixen is the real star here, particularly for its size-inclusive tops and pencil skirts (which come in up to a 4X!). Don’t sleep on the kinky/cute lapel pins and hoop earrings, either.}
The classic style of the pin-up originates back from the 1940s. Due to the shortages of materials during WWII, this period of makeup is considered the "natural beauty" look.[20] The US was immersed in war-time economy, which put distribution restrictions on consumer goods.[21] General rationing was supported; women applied mild amounts of products. Despite the rations, "Women were encouraged to keep buying lipstick and to send letters to the front covered in 'lipstick kisses' to boost the morale of the soldiers."
