I purchased the Gerber Newborn & Infant's 3-Pack Long-Sleeve Onesies and they are great, I love the quality of this brand. Although they do run a little small.
I love Gerber onesies because you can use them everyday and in every season. I can use them in layers and help my baby be cozy.
Onesies are good, run a touch small compared to other brands. They sent me short sleeved non-onesies though, so had to go exchange in store. I ordered 5 items and got 3 incorrect or incomplete items with in one order. Better quality control is needed at the distribution center!
Great fit and good to wear underneath wither apparel.
