Not very knowledgeable about fabrics and elasticity but this was a disaster for me .. 5’ 2” -165lbs .. ordered a large and the pants barely fit .. it was soooo uncomfortable I couldn’t function. I didn’t bother trying on the top.

I was very excited to find an outfit with this reflective material. Sadly, when I tried it on it did not fit at all. I was prepared for this and ordered 2 sizes higher than what would be my normal size and it still did not fit. The material does not stretch one bit, which would make sense if it was windbreaker material, but this material does not search one bit. The top was super tiny and it was an Xl. If I had sat down the pants would have ripped from all sides. On the bright side, the outfit was reflective as shown in the photos.
