When to Wear Girls' Costumes

As a savvy mom who's always thinking secondhand first, it's only natural that you'd want to seek out pre-loved costumes for your little one. After all, Halloween only comes once a year. Why buy new, overspend, and create waste when you can shop like-new, save, and set an eco-conscious example?

You'll be happy to know that if you decide on the right costume, you can stretch your shopping budget and green lifestyle even further. Encourage your little one to wear her fairy princess costume for dress-up sessions. Salvage pieces of a multi-part costume, such as a set of wings or a leotard, and use them for play or in next year's costume. Consider buying this year's Halloween costume a little large, and then add a few new details and have your little one re-wear it next year.
