Kenzo Tiger Sweater

I got my gray Tiger sweater today! Will post pics tomorrow, as it's still in my hubby's car.
Was on the waitlist at the Kenzo boutique (Brussels, Belgium) since early January and got the call yesterday.
So happy, can't wait to wear it!
 
Would the lucky ladies who own KENZO Tiger sweatshirts & sweaters please share some details regarding the sizing ... I heard that they run small, and if in future I have the opportunity to purchase one myself, I would appreciate if I had a better idea regarding the correct size.
It will have to be online, since there are no KENZO stores where I live so I won't be able to try it beforehand, and since they sell out so fast it is highly unlikely that I would be able to exchange it ...
 
The women's sweatshirts run really small. I'm usually a S or M in women's, and the S was way too tight. The M is pretty form-fitting and quite short (I'm 5'7" and it comes just to my waist). I guess they are meant to be fitted. I can't comment on the men's sizes as I never tried one on. HTH.
