I ordered this for my son for a wedding. It was a good deal and fit well. However, he usually wears 18-24 month clothes, and I ordered a 2T and it fit perfectly, so better to order one size up. For little ones, it might be a tad hard to keep the suspenders up around the shoulders. It was for us. If that is essential, consider finding a way to get them on there (double backed tape? a safety pin?). Overall though we were very pleased with the outfit. Adorable!
