👶 What to Wear Under a Baby Girl Dress: Leggings vs. Tights?
This is one of the most asked questions on parenting forums and Reddit threads—and for good reason. What your baby wears underneath a dress can make all the difference in comfort, diaper access, and even style.
👕 Bodysuit Basics
Start with a soft short-sleeve or sleeveless bodysuit (onesie) under every dress. This helps:
- Prevent rubbing from seams
- Add an extra layer of warmth
- Hold the diaper in place
🧦 Leggings vs. Tights
Tights are great for cooler months or special occasions, especially under formal dresses. But make sure they’re soft, stretchy, and not too tight around the belly.
Leggings are more practical for everyday wear. They’re easier to remove during diaper changes and can double as a backup outfit piece.
“I always use cotton tights for weddings, but leggings for daycare and daily outings.” — Mom on Reddit
✅ Pairing Tips
- Use bloomers over leggings or tights to complete the look
- Choose solid-color bottoms to balance patterned dresses
- Always check for bunching or tight elastic

- Always wash new dresses in baby-safe detergent
