Hello � � For a height of 165 and weight of 75 kilos, since the structure of our product is high waist and a mold that fits the body, it seems that ** size L/XL might be more suitable for you **. You made the right deduction, sir. ✨ However, if your waist and hip measurements are wider/narrower than normal, this may affect your choice. If you don't want it to cling too much to your body, we recommend you consider the L/XL size option. Thank you for your interest, we wish you pleasant shopping. � �
