🐎Fouganza black kids riding equestrian pants, size small to medium

Black kids Fouganza horseback riding pants. purchased in Mexico when my kids were riding there. I don't see tags on inside to see size, see pictures next to other kids' size large beige Kerrits and size 12 Fouganza pants (also for sale). I'm guessing small or medium. These pants fit my kids when there were age 6-7. can measure if requested. note some pulls/imperfections in pictures, but these pants are great, have really held up.
