Testimonials
At Next Size Up, we're parents, too — juggling messy meals, sudden growth spurts, and never-ending laundry. This business was born out of a real need: making clothing for fast-growing little ones more practical, more affordable and less wasteful.
Hi, I’m Mae — mom of 2 amazing kids, and founder of Next Size Up. I created this company to make shopping for children’s clothes more simple, sustainable, and affordable for every family.
We collect gently used baby and toddler clothes (Newborn-5T), sort and curate them into stylish, size-specific bundles, and deliver them to your door - making it easier to keep up with growth spurts without overspending or over-consuming.
But Next Size Up more than just a shop.
With every bundle sent and every bag of clothes passed on, we aim to:
✅ Make shopping by size - not guesswork - easy and reliable
✅ Extend the life of high-quality clothing already in circulation
✅ Cut down on textile waste and overconsumption
✅ Support families with more affordable access to essentials
✅ Create a cycle of care that grows with our kids and our values
We're proving that small actions (one outgrown shirt, one hand-packed bundle) can spark real change.
Because at Next Size Up, we believe every growth spurt is a chance to grow greener, give back, and do better. Together. 🌱
