first-bday-outfits-241637-1510264042958-image — Avoid wearing white. Try out a fun pattern instead.

Lastly, these are young kids we're talking about at a first birthday, and they're liable to be messy at times. Leave your crisp whites at home because the probability of stains is much higher than at any other occasion.

Shop printed pieces:

Violeta by Mango Floral Print Blouse ($80)

Reformation Carina Dress ($248)

Victoria Beckham Printed Skirt With Cotton and Silk ($1590)
