We recommend ordering your child's usual size for the best fit. If you prefer a roomier fit or would like your little one to have extra growing room, consider sizing up. For a more fitted, athletic look, choose their current size. Many customers love the slightly snug, uniform-style fit for sports outfits, while sizing up provides a more relaxed fit that can be enjoyed longer. If you're between sizes, we're always happy to help you choose the best option.
