The size I ordered was a size 4. My daughter is a petite 3 year old so I was shocked that after washing them they were snug. They will fit her for a few months but I would have gone one size larger if I knew they were going to be small for a size 4.
My other irritation is the color variety that I received. It was not as pictured, but instead a variety of orange and blue and some had the number 50 on them as a pattern. They reminded me of football. LOL.  Not girly at all. Maybe more suited for a girl that does't like pink.
These will be back up underwear for grandmas house or otherwise I would have returned them.
Overall, I like the material, the fit and the stitching. They seam to cover the bottom well and not come up to high.
