How to Choose the Right Costume Dress

A few practical checks help you pick a size and style your child will wear happily.

  1. Match skirt length: Compare the listed skirt lengths to your child's usual clothing length to check where the hem will fall.
  2. Consider activity level: If your child runs and climbs, choose the larger size for more freedom and longer wear.
  3. Look at materials: Polyester tulle and sequins look showy and are durable, but avoid rough trims against sensitive skin.
  4. Plan for layering: Add a thin tee or leggings under the dress for cooler weather or extra coverage.
  5. Care and storage: Store flat or hung, and follow gentle cleaning methods to protect sequins and tulle.
Frequently Asked Questions
What sizes are available and what do they mean?

This dress comes in two sizes, 3 to 4 years with a 17.7 inch skirt, and 5 to 7 years with a 22.8 inch skirt. Compare those skirt lengths to your child to choose the best fit.

How do I wash and care for the dress?

Spot clean when possible, or use a gentle machine cycle inside out with cold water. Lay flat or hang to dry to protect sequins and tulle.

Are the sequins safe for children?

Sequins are decorative and securely attached, but they are small parts, so supervise young children and avoid use for toddlers who mouth non food items.

Can my child wear this in the water or as swimwear?

No. The Lorelie dress is designed for dry play, parties, and photos. It is not intended as swimwear and prolonged water exposure can damage sequins and tulle.
