Argentina Windbreaker Shorts Set

I wanted to refund the items as its not true to size and feels as if a L is a M and I usually wear M jackets and the L still felt too tight yet they refused a refund and started adding a 24.95 GBP REFUND FEE which they didnt clarify on their website in any instances so i would refrain from ordering from them if you do not know your size and also dont pay for the priority shipping 7.99 as they delayed my shipping by a week and a half ontop of the aclaimed 2 weeks
