hehe i've snap pics for both size. not so much different between both size. but seems that 42" is a bit tight on the chest. i dunno how is ur body size.but for me, if u wanna looks like valencia, then go for 42".  44" more comfort for me.but notice that the sleeve of this away kit is a bit tight and if u have a big biceps, its look nice when u wearing it

this is the pics

L size (42")
