Pink one is Amazing
I purchased this in pink and blue because they are so cute. I washed both together; inside out, cold water, tumble dry low. I tried putting my little in the blue one and it does not fit at all. She fits perfectly in the pink one. She's not a chubby or long baby, so it's not her by any means. I also noticed the pink and blue versions of this feel completely different. The pink one has a smoother softer feel than the blue one which feels stiffer and not as soft. Overall I love the pink bunny version and so does my little.

Adorable and easy
A good 80% of my baby’s wardrobe is this onesie, and for good reasons. They are comfy for her, easy to get on and off, the two way zip is spectacular, I love the little tab that keeps the zipper pull from touching her skin. I love the style and prints, all of them are adorable and don’t fade or crack in the wash.
