I ordered the 6 pack in black/white color size 18 month for my 10 month old to wear now (will be big) and grow into throughout the summer. The quality is excellent, especially for the price. Soft breathable 100% cotton fabric that washes and dries well. True to Carter's sizing - possibly a touch stretchier because of the soft cotton material and no stitching/screen print design etc. to keep the fabric from giving. The designs are adorable and each is very different from the other. These will be perfect to dress up if need be or for him to be comfy at home. I especially love the button details on the submarine, grey stripe, and black onsies. There is also a onsie with a pocket square detail, which is adorable. Definitely recommend the Carter's Simple Joys overall, and really love these onsies. As cute as Cat & Jack at Target in my opinion.
