Blue Collar is an eclectic rock/punk band out of Philadelphia. They have been together for over ten years, and continue to create amazing style-crossed music. BCPA, as they are affectionately known, have done it all; Opening up for Sugarcult and Phantom Planet outdoors; Packing the local pubs with their loyal fans; or driving ten hours to Vermont to wow an audience of twelve strangers. The music of Blue Collar is deeply rooted in the punk rock genre, but seems to break the stereotypes of a typical punk band. Within the elements of their music you hear some rock, a touch of hip-hop, funk, ska, and reggae. Whatever style you call it, the music is memorable and worth listening to over and over. The members of the band are as close as brothers. Tragically, one of the brothers was killed in a car accident in November of 2004. Front-man Vinny Green had a smooth, undeniable voice that has fast become the inspiration for the bands' future. Despite the hardships, Blue Collar has never faltered in their mission to create, perform, and amaze.

Someone who is preppy appreciates classic, conservative clothing. Contrary to popular teenage misconceptions, preppy people do not wear Abercrombie and Fitch, GAP, American Eagle; these clothes are trendy and entirely too flashy/showy for a true prep. Rather, traditionally preppy people wear Lilly Pulitzer, Polo Ralph Lauren, Lacoste, Brooks Brothers, or L.L. Bean. Preppy girls favor simple clothing and jewelry; polo shirts with the collar popped, simple sundresses with a cardigan tied round the neck, or ribbon belts. Preppy males also wear polo shirts with the collar popped, appreciate the simple polished asthetic of khakis, and generally do not dress like slobs.
