Next Size Up is an eco-conscious clothing brand offering affordable, gently used baby and toddler clothes (NB–5T) bundled by size, season and gender preferences. Our clothing is thoughtfully curated with comfort, practicality, and kid-friendly styles in mind — all sustainably sourced and designed to grow with your family. Simply enter the child’s size — or use our Perfect Fit Calculator — with options to share preferences like gender, favorite colors, or styles. From there, we curate each bundle to be soft, practical, and fun — perfect for real-life parenting.
Choose from our options of a full wardrobes, one-time refreshes, or monthly subscriptions based on what fits your needs. Sliding scale pricing is also available for parents who need a little extra support. We believe in accessibility and no gatekeeping for adorable, comfortable children’s clothes. Every order supports our mission to make secondhand shopping more sustainable, affordable, and stress-free for growing families.
We also make it simple to give back: repurpose your child’s outgrown clothes with our free pickup or shipping kit options and help keep clothing in circulation, not landfills.
