actually 84 cm inseam at 178 cm is below optimal leg length - please see my previous post :-
"The "Hip" is not easy to identify exactly, from crotch to floor (against wall, push book up between legs to max, then measure top of book to floor is easiest) or even from greater Trochanter to floor...
The best study (2018
https://royalsocietypublishing.org/doi/10.1098/rsos.171790) on Leg/Body ratio used Trochanter to Ankle height vs Height to gauge Male attractiveness, using this method it found 1 SD above average i.e 0.490+>0.015 = .505 equals best L/H ratio - i.e for me @ 179 cm tall a 90 cm Leg (Trochanter to Bottom of ankle Medial Malleoulus) is most attrractive.
I am currently at 86 cm Leg length, this is after 8cm of LL, and give me a respectable .480 L/H ratio, I was previously at an unattractive 78/171 = 0.455 L/H ratio..."
