Bodysuits for Buddies

Indulge in double the adorable baby girl clothes (and half the dress-up time) with matching bodysuits for each kid.

Comfy and cozy, baby girls up to two years old can crawl around in these soft one-pieces all day. Even better? Every single RuffleButts baby girl one piece and romper is cotton-based, machine-washable, and functionally crafted for easy diaper changes for your little girl. With so many designs, the matching opportunities are endless!

Ranging in price from $13.49 to $22.00, choose from our romper collection for your big sister gift with features like:

  • Tank, short-sleeve, and long-sleeve styles
  • Flower adornments
  • Shoulder ruffles
  • Wrist ruffles
  • Swoon-worthy patterns like rainbow stripes, hearts, and solids

Want to really tip the cuteness scales with your big sister gift? You can even embroider customized initials onto our tops for the big sibling and younger child. A big sister shirt and little sister shirt may be the perfect personalized monogrammed baby gift to show how much you appreciate both of them. Just submit their monograms, and we’ll deliver a photo-ready pair of bodysuits in four to six days—all for just $7.99 more. These are the perfect personalized baby girl gifts!

Ruffles for Sisterly Summertime

Double the butt ruffles, and you double the cuteness. From leggings to bubble shorts, we offer our signature RuffleButts design for all baby girl pants up to size 2T. Plus, if big sister needs a big-girl size, she can still rock the same pattern as her little sister—without the ruffles.

With at least 95% cotton and machine-washable fabric, our girls' bottoms are built to last and pass down. Mix and match adorable patterns across designs like:

  • Capri leggings
  • Bubble shorts
  • Play shorts (athletic/everyday play)
  • Ruffle pockets & ruffle trim shorts

Don’t forget to catch our sales! Keep an eye out for shorts as low as $9.99—it’s practically a two-for-one price.

Head-to-Head in Headbands

Does the older sibling want to rock her own clothing? Choose a subtle matching accessory for your daughters like cute bow headbands.

Our Big Bow Headbands are the perfect accessory for any girl’s outfit. Made with cotton, modal, and synthetic materials, these soft headbands fit snugly around little heads for a secured hairstyle and will be a favorite for older siblings as well as the younger sibling. Our Big Bow Headbands are one-size-fits-all and have:

  • 20+ color options
  • Comfy elastic fits
  • USA-made designs

With coordinated headbands, the older child can keep her individual style and proudly match her little sister—and at $10.00 each, these quality headbands are practically a steal and are the perfect gift to welcome a new sibling.

Twins in Twirlers

Nothing says “We’re sisters!” like matching dresses. In RuffleButts dresses, big sister will feel like the stylish lead to little sister.

One pieces, footsies, short-top combos, pant-top combos—our cozy sleepwear can fit any season and are some of the best big sister gift ideas out there. We use natural textiles like cotton and modal for snuggliness, and just a touch of spandex for stretch. Even better? Your girls will never slip or struggle in RuffleButts baby girl pajamas and girls pajamas for kids. Functional details ensure all-night comfort, such as:

  • Elastic waistbands and ankle bands
  • Tagless necklines

Mix-and-Match Your Misses

Maybe big sister likes to wear the pants in the family—or maybe little sister needs shorts to crawl easily every which way. Whatever the case may be, your angels can still match in different pieces of clothing—all thanks to our crossover patterns.

Between tank tops and rompers, RuffleButts offers the same fabric patterns across our entire girls collection. This not only makes dress-up time a breeze, but it also opens the door to so many sister outfit duets. From $9.99 to $35.00, you can buy matching separates in seasonal patterns and colors like:

  • Baltic Blue
  • Darling Bouquets
  • Cottage Flowers
  • Autumn Plaid
  • Denim
  • Rainbow Hearts
  • Ballet Pink
  • Chasing Rainbows

Plus, every clothing piece at RuffleButts is made with quality in mind—think cotton-based fabrics, USA-made designs, and machine washability, so your personalized gift is a very unique gift. Whether big sister rocks a dress or romper, the older sibling will have an outfit to last for plenty of hand-me-downs to come.
