Because onesies are fun to wear, they are often made in all sorts of bright colors and fanciful patterns. But they are also made in more sober colors, such as grey and black. Bright colors might be fun at first, but it’s the kind of thing you may get tired of quickly. If you think that could be the case for you, then you may want to get something black. Whatever the color, a onesie should be soft and comfy. Look for models made of fleece, as they are probably the warmest and softest.
I like these – the black color makes them less silly, but no less comfy:

Onesies are not the kind of garments that have to fit perfectly. This is strictly around-the-house wear, so you shouldn’t worry too much about how well it fits. Comfort is the important thing.
