Jacket Size Large

What size is a size 38 jacket…small, medium or large?

I found a classified article about a leather jacket for sale. I know what size my other jackets are…but they only say size x-large. The classified however says size 38. What equivalant size is this…small, medium, large or x-large?

somtimes it’s like this:

32/34 = extra small
36/38 = small
40/42 = medium

but sometimes 38 is considered medium.
