Key Pieces for a 21st Birthday Outfit:

Before we get to the fashion picks, here are a few must-have items for a 21st birthday look:

  • Crossbody, wristlet, or clutch with wrist strap – For a crazy night out, you don’t want to be burdened by a heavy bag – go for a wristlet or clutch that attaches to you so you won’t lose your money and ID.
  • 21st birthday tiara, sash or light-up shot glass – These are optional but so much fun! Aside from perhaps a bachelorette party, a 21st birthday is the ONLY time you’ll have a built-in excuse to look completely ridiculous at the bars and at restaurants. It’s your birthday, so live it up!
  • Flashy heels – It’s your birthday, so why not make a statement with your footwear? Something sexy, sparkly, or bright is a must for your 21st!
  • Amazing dress – Your 21st birthday is the perfect opportunity to splurge on that perfect party dress -go for something you absolutely love, and make sure it’s something you’ll be able to dance in. 21st birthday dresses are supposed to be fun!
  • Lipgloss – You’ll want to freshen up as the night goes on. Glossy lips are always a bonus.

  4. I wore jeans and a nicer shirt for my 21st birthday, but then again, I am a summer baby, so I didn’t have a bunch of friend’s around for my birthday. At least I didn’t get alcohol poisoning from that birthday!
