What's a good place to get neon clothes?

You can find neon pink, green, yellow, orange dresses at your local DEB all year round, and you can find them also at JCpennys around the time of prom. The sizes go from very large. Also small as to fit the average 11 year old can fit into at DEB JCpenny anyhow goes as small as the average 10 year old can fit into.
