Is it better to wear smaller singlets for wrestling?

Question

if you wear medium wrestling singlets should you wear smaller. It seems to be the new "thing" but i don't seem know why. Seems pretty stupid but say what you think.

When i wrestled in high school i preferred a bigger singlet as they were more loose and meant i could move around much more freely.A smaller singlet is tighter and will restrict your ease  of wrestling.

Answer 2

bigger singlets are better
