I have three, but third is grown and long gone from home so I mostly just talk about the two! I have a big age gap 15 years between first and the other two. I also shop JCP/Childrens Place, mostly Target is my favorite for them on fit/price/convenience, occasionally also Old Navy and
Walmart, just picked up some swimsuits at Walmart $8.96 for them. Sizing and brands are always so different, it's hard to figure what's best but my best size/fit, currently is with Cat & Jack and C9 brand from Target. I can pull a size 12 pants at Penney's and it's so long yet so narrow waisted, the same size 12 isn't nearly the case at Target. My youngest is tough on pants, I replace a lot during winter season. Size 12 or 14 shirts. Frustrating when shopping for kids, glad when shorts season is here, almost there.
