Size 28 jeans is usually a women's size 6. The waist is 30 1/2 and the hip is 37 1/4th.
Just measure your waist in inches and that's the mens size you need. I would say a 28 is 14/15 from my own experience, but it varies by manufacturer.
I was in a size 28 when my waist was 58 inches around but they were a little tight.
