The Miniskirt
British designer Mary Quant is widely credited with ushering in the miniskirt's popularity in the 1960s, so you know, we just love Mary Quant. Trends come and go, but it's been around ever since.
The Stiletto
High heels have been fashionable for centuries—even Louis XIV wore heels at Versailles—but no one thought to put a metal splint inside the heel until the early 20th century. By doing so, the heel could be much narrower than when it was made of wood alone, and hence the pencil-thin stiletto was born.
In 1959, Glen Raven Mills introduced the prototype of modern pantyhose, and in 2013, Kate Middleton is still keeping the industry going strong.
The Bikini
The two-piece swimsuit packed a major punch when it became popular in the early 1940s, so it's pretty fitting that it was called the "bikini" after Bikini Atoll, where the atomic bomb was tested. The silhouette's no longer as shocking, but it's still the swimsuit of choice for most women.
Convertible Bras
We just keep thinking about all the women who'd go bra-less with their party dresses in the '70s and '80s and feeling bad for them. Now that convertible strap bras like this are so easy to find, there's no reason to forego support if you want it.
Size-Matching Technology
Some stores have tested out body scanning machines, but our favorite size-matching advance helps with online shopping instead. It's called TrueFit, and it quizzes you about your body type, inseam, favorite denim brands and other information in order to steer you towards jeans that will fit you the best. You might not know that, say, J Brand jeans fit really differently than Joe's Jeans—but they do. Technology, it's great.
Synthetic Fabrics
Polyester was invented in 1935, nylon in 1941, and spandex in 1959. All three fabrics have not only changed the way we dress, but also what we can do in our clothes, like run for miles while staying warm and dry the whole time.
Digital Printing
New technology doesn't just mean new fabrics; it means new ways to alter the fabrics, like digitally printing them with hyper-realistic scenes like this. It's like wearing a photo on your body, and it's awesome.
