Frequently asked questions

Can I buy matching clothes for siblings (brother & sister)?
Yes. We offer big brother little sister matching outfits and matching sibling sets that pair our big brother short sets and shirts with girls’ dresses or bubbles in coordinated fabrics.
Do you offer big brother short sets?
Yes — our big brother short sets include coordinating tops and shorts in classic gingham, embroidered, or solid styles designed to mix and match.
What sizes do big brother outfits come in?
Our big brother pieces are available in toddler and big kid sizes like 2T, 3T, 4T, 5, and 6. Use filters to view in-stock sizes.
Can I personalize a big brother outfit?
Big brother outfits are pre-embroidered with “Big Brother,” so personalization or monograms are not offered. The embroidered design is included.
Is monogramming available for big brother outfits?
No — because our big brother styles already include the embroidered “Big Brother” label, we do not offer additional monogramming.
What makes a good outfit for a big brother announcement photo?
Pair a classic big brother short set or shirt with coordinated siblings’ styles (dress, bubble, etc.) to create a cohesive look for announcement or gender reveal photos.
