Hello � � First of all, thank you for your interest. This suit has a regular fit and comes in two sizes: S/M and L/XL. Since you are 150 cm tall and weigh 78 kilos, there is a possibility that the S/M size may be too tight, and the L/XL size may be a bit long, especially in the length part. However, please note that size L/XL may be more comfortable as it has a comfortable cut. The hem length may seem a bit long for you; if you wish, you can have it shortened at the tailor for a better look. The product's crinkled weave and regular cut will provide you with an advantage in terms of ease of movement. � �
