Also I don't think the onesie is too heinous, or rather isn't any worse than any other onesie. My opposition to onesies is that I don't want to take my top off in order to go to the loo! I did get a fleecey poncho pyjama top thing for Christmas though and really like it though 
It's this.
Before I get chased out of S&B forever, I would never wear it outside the house! Strictly nightwear/loungewear.
