True vintage clothing was produced in the era you are trying to portray, whereas retro clothing looks like it’s from that era but was made more recently. Retro is a copy of the real thing produced in mass market, whereas vintage is the real thing. If your clothing was made before the eighties, check for the “Made in the USA” seal or whatever country you are situated in. On the tag there should be a union name and ID number. A tag that says “Made in China” is a sign that the article of clothing is not vintage.
To hit the jackpot of vintage style, locate that crumpled up underskirt that you were forced to wear once underneath a hideous bridesmaid dress when you were a teenager, but couldn't bear to part with for sentimental reasons. Maybe you were a dancer or have some dancer/actor friends who are bound to have an underskirt in every color of the rainbow from their various performances. If you manage to get ahold of one, it really does make a swing dress sing.
Collectif Clothing: Collectif focuses on 1950s glamour with four distinct brands. Playful tropical prints, gingham dresses, and kitschy circle skirts make up Collectif Mainline. If you want a more subdued look but still prefer colors and patterns, like this fan-favorite pencil dress, you’d enjoy the Vintage line. Lulu Hun is the shoe collection, comprised of very rockabilly flats, sandals, and heels. And Bright and Beautiful is the latest line, with ’70s-inspired caftans, mini dresses, and accessories. All styles are designed in-house.
You can’t be anything but eye candy in vintage inspired pin up dresses with A-line, pencil or circle skirts that dance with your every step.  A wide cinch belt helps define your waist and add a contrasting color to your pinup fashion. The strapless, spaghetti or halter neck pin up dresses are the most popular 50s pinup clothing for summer.  Pin up dresses with sleeves are harder to find however with a little crop or cardigan sweater sleeveless dresses are wearable all year long.
Do you or did you used to work in an office environment? Then you're bound to own a pencil skirt. The classic pencil skirt is a key piece to bring to a pinup shoot as it's very usable and can be worn with shirts and cardigans or even just with your favorite bra. It is reminiscent of 1950s wiggle dresses that made the wearer walk with a little wiggle in their step.

I think this is my favourite Chic Star pencil dress so far!  It's made from poly/elastane stretch fabric in a gorgeous midnight blue. The fabric is lovely and soft and smooth against the skin. My favourite feature apart from the lace is the ruched bust. Definitely a great dress to wear to work or for an evening out. My measurements are bust 90cms (12DD bra), waist 69cms and hips 93cms and the size 8 is a perfect fit. If you have any questions, please get in touch!

Women usually chose a pair of cigarette pants with side or back zippers. These pants were cut full through the hips tapering to slim- fitting legs. Most cigarette pants ended just above the ankle allowing women to show off their stylish footwear. They had a high waist usually accentuated with a 3 inch waistband. Some women broke up the wide waistband with a thin leather belt. Early on, these pants were mostly black, but by the end of the decade women were expressing their own unique style by wearing stripes, leopard prints, checks and polka dots. Consider adding a pair to your wardrobe by getting these from Unique Vintage (@uniquevintage)

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."
