take a jersey you like. place it flat, no creases, on a table, front down. measure between the armpits using a tape in cm. look at the sizing chart, first table, on row F and choose the column which is the same as you measured, or slightly larger. use the number in brackets at the top of the column. if you are larger than the largest column, use 6.
if you care more, use more measurements in different directions, think, and make a decision based on the fit you want.
similar for bib and second table. really this isn't that hard. i've just had a pisco and i can work it out.
