20. Don't Stay In Your Age Group
Fashion has no age - when designers drop collections they don't say "THIS IS FOR TWENTY YEAR OLDS ONLY." Which means you can dabble in whatever styles, silhouettes, or subcultures you want to. If you like what you see in Zara, Forever 21, or Mango, by all means, try it on. Lanvin model Tziporah Salamon isn't exactly wearing Chicos here, and she looks fabulous.
