Gothic Lolita (or Goth-Loli as it is sometimes known) is a form of Lolita fashion. Lolita fashion is a form of dress much popularized in Japan, worn by young women. This fashion style became popular during the late 1970s, but the exact date of origin is still unclear. Women that wear Lolita styled clothing wear many frills, knee-high socks, platform shoes, and stockings along with many other accessories.
Gothic Lolita is slightly different from typical Lolita fashion. With Gothic Lolita, much of western “Gothic” style is incorporated into the sweeter Lolita look. This means wearers of this style usually apply heavy makeup around the eyes in darker colors, the colors they take to wearing in general become darker (often black is used). Accessories carry more morbid shapes such as crucifixes, bats, or Fleur de Lis. A fictional character, Amane Misa, from the hit manga, Death Note, dresses in the Gothic Lolita style.
For this look, you must invest in a few essential items: These include (but are not limited to) a white blouse and/or a black blouse (depending on what style your wardrobe is leaning towards), one or two full skirts, a good petticoat, bloomers, and knee-high or over-the-knee socks. Blouses vary with style. Other elements to look for in a blouse are a nice, tailored look, puff or cap sleeves, a bib or yoke, pintucks, ruffles or a decent amount of lace, and perhaps a neck bow if you wish. The skirts must be around knee length and full enough to fit a petticoat underneath. Also, make sure that the skirt fits on your waist or a little below it, but not at your hips. In order to get the right silhouette, the skirt must sit at the natural waist. A good petticoat is NOTHING like a square dancing petticoat. A-Line or Bell shaped is recommended. Hoop skirts and light slips will not fill out the skirt correctly.
