I only need one for 2 mths of the year but can't seem to find one on line that would fit

The sizing charts have the right chest but I need 6 inches added to my legs XXXL

The size that fits (acording to measurements ) has me having to fit into 103cm chest.(that will make my eyes pop out and you know what shoved up my rs
measurements are :- 180cm tall
123cm chest
100cm waist
93 kg
Anyone close to this? if so what the fek fits XL, XXL XXXL ??
Or should I just give up and go without in 16c,

What do ya recon ?
tgcp any ideas
