What to look for in the best baby Halloween costumes

• Safety: Safety is one of the most important things to consider when choosing the best baby Halloween costumes. Besides, you won't want to purchase anything that poses a choking hazard. However, you'll also want to consider buying a costume that's visible in the dark, especially since trick-or-treating takes place at night.
• Comfort: Relaxed, comfortable costumes like onesies and jumpsuits are always a great choice, as they have easy zippers for on/off and are snug and warm as a pair of pajamas. Don't want to let a messy diaper ruin your baby's Halloween fun, so look for costumes that have snap closures at the crotch for easy diaper changes.
• Materials/Quality: The best baby Halloween costumes should be able to keep up without snagging or tearing. So, as you select a Halloween costume for your baby, it's important to choose pieces that are both well-crafted and constructed from soft yet durable fabrics. Look for cotton, fleece or thicker, well-made polyester.
