This is from a Marine officer who was saying the same thing on another site who had:
2. Flight Suit for flying. One piece coveralls in different materials, designs and colors, depending on assignment. In Vietnam I wore a tiger stripe flight suit, there was also Olive drab, Marine Green, International Orange, and Khaki.
3. Summer Class A uniform, spiffy khaki belted tunic and matching trousers in a good material.
4. Winter Class A uniform, same design but Marine Green and a very good quality of cloth.
5. Summer Dress White Uniform, high collar white tunic without a belt, and matching white trousers.
6. Dress Blues, High collar black belted tunic, with blue trousers with a wide red stripe down the leg.
7. Mess Dress, elegant short shell jacket with high collar, shoulder boards, sleeve embroidery, worn with a formal dress shirt and cumberbund, elegant trousers with gold and red stripe.
8. Summer Work Uniform, short sleeved, open collar khaki shirt, and Marine Green trousers of a lighter weight than the Winter Class A uniform trousers.
9. Physical Training uniform, shorts, tee shirt, and athletic shoes.
10. Marine/Seal/UDT swim trunks, very distinctive khaki short shorts with a little half belt in front. You see somebody with this suit on and you knew immediately who he was.
