After making the perfect t-shirt, The Willie T-Shirt, we knew could take it one step further by creating the most perfect unisex onesie, and here it is! We spent forever and a day finding the best fabric, making sure that it wouldn’t stretch out with wear, making sure that it was extra soft, and making sure that it was easy to get on and off with our snaps at the back of the neck and diaper (in our signature colors). We made all of our dreams come true and are so happy to finally give you the world’s most perfect T-shirt Onesie.

This is a core item. We keep our core items available year round as they are the foundation of our brand and an essential part of your child's wardrobe.

      Really cute details

      Seems like a simple onesie, but the piping details and the multicolored buttons at the neck make this special and a bit elevated -- I immediately bought one in another color. Also appreciate how the buttons make this easy and comfy to slip over his head. Will say that the snaps at the crotch sometimes feel as though they're straining and have been known to pop open -- admittedly my toddler is extremely large for his age, but the next size up is still a bit roomy for him.

      Cute and quality wardrobe staples

      I sent a handful of items that can be mixed and matched to a dear friend who's expecting her first child. She was so pleased with the quality and versatility of the clothes.
