The size chart makes no sense... it lists american sizes (12, 14, etc.) but the sizes are in med-large-xlarge etc. so this information isn't helpful?

I am a 5’8 and a 12 or 10 (31 or 30) in pants (depending on fit) and a medium top. I got the large and it fits me perfectly.

I am 5'8" and 135 lbs. I need these to also fit over clothes so what size should I get?

The size guide on the Dickies Website is accurate to size for wear as a primary garment, so measure over your cloths to wear as a second layer.

I'm confused on the size chart. it specifies inches for sizes in 4, 6, 8, etc. but when you go to order an item, it's xs, s, m. is a 4 a s or xs?

4 is XS, 6 sm, 8 & 10 like a medium

I am 159 cm which one should i take? M or S

I am 4’9” tall and I ordered the small, it is long on me, but fits in all other areas just fine, it’s just long since I am under 5’. I have to roll up into a cuff two times so I don’t step on it to walk. I only wear it when I’m gardening.
