Looking to buy an amoresy but what size?

Hello! Hopefully you can help; I'm looking to buy an amoresy for the first time but I am a bit confused with what sizes to go for. I'm 174cm tall, with 30" waist, so should I go one size up or what? I don't want the amoresy to be baggy. I like a good tight fit :) Thanks.

183cm, 86kg, ~32" waist here. I use different sizes for different models. - Athena Catsuit XXXL - Athena Superfine Sheer Catsuit XXL (the additional stretch enables me to wear it but it's super super tight, not sure if others like it this tight hehe) - Gladius Sports Unitard Suit XXL - Jupiter Long-Sleeve Sports Top XXL - Jupiter Long-Sleeve Sports Top XXXL I'm not exactly your measurements, but maybe it gives you a better idea

My measurements are similar to yours 175cm 32” waist 70 kg I purchased a 2XL Fits nice and snug. Only issue - zipper is in the back, can’t get it to zip up.

Hi, I am also looking to buy my first Amoresy catsuit and I am also unsure which size to get. I am 176cm and 76kg.

Try tying a short length of nylon braid/cord to the back zipper. Like surfers use on their wetsuits. That will allow you greater ease of zipping it up. It's a bit much to manage if you aren't double-jointed, and don't have a friend there to help.
