Our size guides are based on height measurement and two additional parameters depending on product type.
A few rules to help you with picking correct size:
Female with body measurements 165cm height, 94cm chest, 103cm hips should choose size M and select REGULAR FIT option from "Fitting" drop down list.
EXAMPLE 2
Male with body measurements 175cm height, 94cm chest, 86cm waist should choose size L and select SLIM FIT option from "Fitting" drop down list (selected by default).
