The material and fitting is very good. I would recommend to size down if you want a perfect fitting suit or if you don't have time to alter. I purchased a 4T and 5T for a 5 year old with longer torso compared to legs. The 4T ended up as a perfect fit with no room to grow whereas for the 5T the pants ran a little long but other pieces were perfect.

Nice Brown

The suit looked very nice. The fabric is good quality if it’s great for the size that is supposed to be I would say the only thing that gives me a little concerned with the pants are a little short but other than that, it’s wonderful. It looks amazing.
