This is a nice looking cap from Kangol - my girlfriend in particular liked how it looked on me.  Unfortunately, when this arrived I discovered my head isn't the 'normal' shape - long oval in hat terms.  This means the cap was tight front to back, and loose on the sides.  So if I got a bigger size it would fit front to back and be very loose on the sides.

The way the cap is constructed, it doesn't conform to the shape of your head, but instead tries to hold its blocked shape and pull your head to match!  For most this is a good thing because the cap keeps a good shape, but I got a headache.  I have since tried some Brixton caps which are much more comfortable for me (and sell on Amazon for similar prices).
