The sizing on their website is really off. I'm a 38" chest, and according to their size advisor for this item size 42 fits a 35" chest. I ordered size 42 anyway.
I tried it on and lo and behold its way bigger than 35", or even my 38" chest! Even though its too big for me a size 42 is listed as 35" chest? I contacted the web online chat, and he wasn't much help.
Any ideas on what size to go for? They have sizes smaller than 42, but the size advisor doesn't show approximate sizes for them. And even if they did, I'm sure the smaller sizes would illustrate a a chest size smaller than 35", which suggests to me that it is really inaccurate.
TLDR; I am 38" chest. Ordered a waistcoat size 42, which is supposed to be size 35" chest. Size 42" was too big for me, even though it was supposed to be 35" and I'm 38
Edit: I know SS do free returns but I can't take the financial hit to order several items in one go unfortunately
