Size Guide
Every Unique Baby outfit is sized by the garment, in inches, so you can match it to something that already fits. Measure a favorite tee or dress laid flat and compare. Kids sizes run 12M through 12Y, grown-up tees and pants run XS through 4XL. Sizes 2T through 5T on Amazon are the same garments as 2Y through 5Y here.
Between sizes? Size up. Our prints are made to be worn for a whole season of holidays, and a little room means it still fits at the last one.

How to measure
- Length. Shoulder seam straight down to the hem. For pants and leggings, waistband to hem down the outside of the leg.
- Chest. All the way around the garment just under the arms. Lay it flat, measure across, and double it.
- Waist. All the way around the waistband while it is relaxed, not stretched. Elastic waists have a few inches of stretch on top.
- Sleeve. Shoulder seam to the end of the cuff.
