This study carefully explored today`s preferable beauty images, analyzed Korean adult purchasing trends of functional underwear and market analysis of the most popular items and their designs. Information and methods are based largely on reference book material as well as analysis of real domestic data. The paper`s research timeline simply spans the last three years, as in accordance with project parameters. Helping improve body shape, foundation literally means ``substructure`` and ``base``. The formativeness in these adult foundations typically has three main category classifications. First, natural modem image. This is where we find natural beauty including that which embodies a cool modem sense. Here, you can often see such patterns as either stripes and dots, or simply no patterns at all. Colors are green, red-brown, incarnadine, or khaki from a natural or basic human body color. Its products are marketed as both solid and durable eco-friendly materials, and lace-seethrough. Fashion`s natural modem image is undoubtedly the most popular style purchase choice among both genders. Second, sweet romantic image. This mainly consists of two concepts: a sweet and romantic theme, and visual appeal. Patterns include flowers, lips, hearts, stars, candies and various other appealing characters. Its main colors are pink, yellow, red, purple, and violet. Products are decorated with laces, frills and ribbons. Since only men`s semi-girdles carry such designs, this fashion foundation is largely a women`s world. While men show an obvious interest in foundation, they still mostly prefer the choice of natural modem images. Third, mystic sexy image. This is defined as all feminine images of mysterious and classic sexual beauty. Patterns are variously expressed as paisley, flowers, and geometric. Colors are largely purple, blue-green, royal-blue, cobalt, and black. Products are commonly decorated with beading, spangles, hot-fixes and so on. While this image can be found in all kinds of women`s foundations, it typically appears only in men`s corsets and girdles.
