I had to buy some BDUs even though I was getting out and they were relatively expensive.
I bought some ACUs for my last two years in. One benefit was you could take them straight out of the dryer, shake them out, put them on the hanger and never need to iron them.
The permanent press fatigues (as in Stripes above) were the same way, but they looked even better ironed and starched. In Korea my housemen did it (never called them “houseboys” they were usually old enough to be my father) but stateside I usually didn’t bother.
