Jarensky represented New York in the Miss USA 2005 pageant held in Baltimore, Maryland in April 2005. She placed in the top ten of the nationally televised pageant, which was the first placement by a delegate from New York since 2002. Jarensky's Graecan-inspired gown was given a lot of attention during the pageant, because of its styling, which was highly unusual for a pageant gown. During the top 10 swimsuit competition, Jarensky almost tripped and fell on the cloth of Miss California USA, Brittany Hogan who accidentally dropped it.
