Clothing size requirements are as follows:

1 S code 160/84

2m yard 165/88

3 L code 170/92

4 XL code 175/96

5 XXL code 180/ 100

In view of your height, you should choose XXL size, but your figure is thin. I suggest you choose XL code. Shirts that don't fit will look untidy, sleeves are too long, and you are fat, giving people a sloppy feeling. And the effect of waist binding in summer is also very poor.
