Last winter I I bought my daughter a 1 piece snowsuit and also received a 2 piece bib style suit for a gift. I used the 1 piece suit only once! She was such a puff ball in it and was too warm to put it on then drive somewhere even a few minutes away. I opted for the 2 piece bibs all season because you could get the bibs on w/ a fleece or sweater and she'd be fine for a short car ride, then when you get where you're going just throw on the jacket and you're ready. Once in the 1 piece we went sledding, then I had to take off her boots to get the suit off just to get her in the car to go 6 minutes down the road....hassle. Go for the 2 piece, you'll get more use from it.
