Fun Tips From a Mom Who’s Been There

• Cardboard + paint = magic (seriously, so many of these can be DIY’d!)
• Raid the dress-up box before buying anything new
• Add a label or prop to make the costume super clear
• Comfort matters, especially for school days or long parties

Alphabet costumes are one of those ideas that never get old. They’re easy, creative, and kind of addictive once you start thinking of them!
