I’ll be the first to admit it—I’m not the mom buying Halloween costumes weeks in advance.

I wish I was! Maybe I will be...someday. But in my current stage of life, between work, kids, and everything else on the calendar, Halloween has a way of sneaking up on me every year. That’s exactly why I love these one-and-done, super unique baby costumes. No DIY projects, no hunting down matching accessories, and no spending weeks planning. Just zip your baby into one of these adorable one-piece (ok, two piece if you count the socks) costume, snap the cutest photos, and you’re ready for trick-or-treating, daycare parties, etc. Even better? Every costume in this roundup is under $30, so you can pull off an adorable Halloween without the last-minute stress (or the hefty price tag). I think baby will love these cozy costumes too :)
