You don't put in your profile where you live, so its hard to give you recommendations on getting custom leathers.
But in addition to getting custom fitted ones, you can look at BMW's Pro-Race leathers which also offer half sizes. For example, a size Euro 52 jacket might fit you fine, but the 52 pants may be long - well they also make size "102 or 104" pants which tend to be 3 to 4 cm. shorter, but with a similar waist size to the 52 jacket.
Look on your local country's BMW web site and you should find a sizing chart.
Other manufacturers may offer similar half-sizes, although I dont think Alpinestar nor Dainese do, but you can check.
