Being on the bigger side at 305 how does the sizing go? I’ve tried the black SDP shirt on and it’s extremely tight and not forgiving in the sleeves. Tried the purple on and it’s still tight but not as bad in the sleeves. Both shirts size 60 and well broken in. Chest measures 55 under the arms and arms measure 22″. Not sure if a stock shirt would be ok or have to pay extra for a custom shirt
