Onesies being sleepwear, you only wear them at home, and that means you can wear them in colors that you may not wear on any other garment. Bright yellow for example, is a color you might not pick for a pair of pants or a shirt, but for pajamas or any sort of loungewear, it’s fun to wear. Look for onesies that are not only colorful, but made of comfortable fabric that will feel soft and cozy. That’s what onesies are all about.
Four examples – I like the white detailing on the third and fourth ones:
