So I won't try here to do something different. I will stay preppy :) Hope you like it!
Here some definitions and history of preppy style... :)
Wikipedia says: preppy, preppie, or prep (all abbreviations of the word preparatory) refers to a modern, widespread United States clique, sometimes considered a youth subculture. Preppy is a chiefly North American adjective or noun traditionally used in relation to northeastern private university-preparatory schools and denotes a person seen as characteristic of an attendee of these schools. Characteristics of preppies include a particular subcultural speech, vocabulary, accent, dress, mannerisms, and etiquette. Preps often are associated with traditionalist, East Coast, upper class "WASP" families in the United States.
The word is particularly well-known amongst American teenagers, as it is quite often used to refer to a particular subculture present within most populous American high schools: the traditionally "popular kids", generally consisting of the children of middle to upper class families, typically characterized (especially by Hollywood in films such as John Hughes' Sixteen Candles and The Breakfast Club) as a shallow, transparent group, who are primarily concerned with extrinsic things, the three most obvious of which are probably popularity (generally within their own high school), physical appearance and material possessions. However, when used in this sense, the word is considered slightly more "slang-ish" when it is shortened to the term "prep(s)".
In the U.S. region of New England, the term is not necessarily pejorative or even related to class, as "preppy" clothing is relatively normative. This style shows preps in a more positive light, as documented in The Official Preppy Handbook. They are painted as a group who are well educated, well connected, & although exclusive, are courteous to other social groups without creating a serious relationship with them.
Brands such as Brooks Brothers, Abercrombie, L.L. Bean, Ralph Lauren, Vineyard Vines, Lilly Pulitzer, Elizabeth McKay, Lacoste,J. Crew, and J. Press are frequently perceived as preppy styles. Examples of preppy attire include button down Oxford cloth shirts, argyle sweaters, cuffed chinos, madras, Nantucket Reds and boat shoes.
In 1980, the author and private school alumna Lisa Birnbach edited The Official Preppy Handbook, a tongue-in-cheek guide to what she termed "prepdom". Birnbach, with Chip Kidd, have authored True Prep, a followup to the 1980 handbook, published September 2010 by Knopf.
Preppy fashion became popular in the 1980s and enjoyed a revival in the 2000s, as did the related style of "Ivy League" or "Trad" clothing.
