Assos bib tights sizing.

Hi guys in a bit of conundrum. I am 178cm 77 kg and my waist is 33" and hip is 38". As per the size chart if I follow my hip size then size S should fit and if I follow my waist dimensions size M should fit me. As per the size calculator it says size M.

So my question is if I go with size S will it be too tight? As per your experience how does the ASSOS tights fit are they super tight or are they snug. This will help me to decide whether sizing down will be a better option for me or not.
