CarharttWomen's, Rugged Flex Loose Fit Canvas Bib Overall

The size selection is small/med/large but the sizing chart is in actual pants sizes. how can i relate one to the other??

What’s the difference from xl and xl short ?

I’m 5’11 and 150 lbs. with a 34” inseam. Usually wearing a size 4/5 in jeans. What size should I get?

I am 5”4 and 165 lbs... I can wear a size 12 in jeans should I go for a medium ? (I plan to lose more weight)
