Yes and becuz of that, it stuffed up my whole sense on wat size
shirts i wear... i think the brown shirt follows the main stream
sizing. The grey PT n Admin follow their own SAF world sizing. Just
like the shorts x)
But like, SAF dun take into consideration how much weight u loose
during BMT especially PTP batch. My No.4 is superly oversized for
me already. Waist all buttoned to max and still will fall off. Knee
area of the pants over my shins even wen pulled up.
