The current USAF service dress uniform continues to include the three-button blue coat. However, as a matter of practicality for daily duty, particularly in warm weather climates, USAF personnel will typically wear the short-sleeve or long-sleeve Shade 1550 light blue shirt (for men) or short-sleeve or long-sleeve light blue blouse (for women) as an outer garment, with or without a tie or tie tab, with applicable rank insignia, speciality badges and a blue plastic name tag (ribbons are optional). A variety of alternate outer garments are also authorized for this uniform combination such as blue pullover sweater, blue cardigan sweater, lightweight blue jacket, or brown leather A-2 flight jacket (A-2 flight jacket wear is limited to aeronautically rated officers, enlisted aircrew, and officer and enlisted missile operations personnel only).
