From a long time Sternberger- the dress code is as follows:
Skirts must cover knees
3rd and 4th graders (of 2010-2011 schoolyear) are allowed to wear short sleeves. All other campers and staff must cover elbows at all times. (they do allow layered shirts too)
campers are required to wear socks that cover their ankles
staff’s skirt and socks must meet.
anything that is not on this list is basically acceptable.
even wacky colors, for reasons that LSS already answered- you really do not stick out for wearing wacky clothes, cuz everyone does. Take my word for it.
