A first birthday only happens once, and the outfit is part of the memory -- the one she'll see in every photo for the rest of her life. Here's how we'd plan the wardrobe for the big day.

You'll Probably Want Two Outfits
Most first birthday parties end up with two looks: a cake smash outfit (something you don't mind getting messy) and a party dress for the rest of the celebration. Planning for both ahead of time means you're not scrambling to change a frosting-covered onesie mid-party.
What to Look For
Comfort for a long day -- soft, breathable fabric with no scratchy tags or stiff seams
Easy diaper changes -- snap closures or simple silhouettes beat anything fussy
Photo-friendly details -- smocking, ruffles, and puff sleeves catch the light beautifully in photos
Our Picks for the Party Dress
The Smocked Angel Wing Dress is a favorite for exactly this occasion -- twirl-worthy, soft, and dressy enough for a party without being uncomfortable for a toddler who wants to crawl, cruise, or take those first wobbly steps. For a cooler-weather birthday, the Baby Blues Smocked Dress layers easily with a cardigan.
A Personal Touch
If you want the outfit to feel extra special, consider a personalized blanket or bib with her name or birthday date for the cake smash photos -- a small detail that makes the album feel like hers alone.
Don't Forget the Guests
If grandparents or friends are asking what to bring, a Gabby Lou Baby gift card lets them pick out something soft for her first year without the guesswork.
