<p>I say 8th grade is generally the limit. Once you’re too lazy/cool to put together a costume it’s time to stop (mostly middle school boys). I guess high schoolers are ok if they’ve made the effort to make put a costume together, are polite and have a fun attitude.</p>
<p>I heard of a great costume this year for groups of girls, teens or older, probably best for a party rather than trick-or-treating. Buy matching short dresses, cover briefcases with foil and put a black number on the outside, and go as the “Deal or No Deal” models!</p>
