public (hence the moniker "walking-out dress"). No 3 Service Dress becomes No 2B Mess Dress by replacing the shirt and tie with a white shirt and bow tie, or to No 1 Ceremonial Dress by the addition of ceremonial web or sword belts, gloves, and other accoutrements. No. 3 (Duty Service): Tunic and necktie, with medal ribbons. No. 3A (Long-Sleeved Shirt): No. 3 with jacket removed; worn only indoors, within DND buildings. No. 3B (Short-Sleeved Shirt): Short-sleeved shirt, without tunic or tie; worn during the summer on less formal occasions. No. 3C (Sweater): Shirt and sweater, with or without a tie; worn in place of No. 3B in cooler weather. No. 3D (Tropical): Alternative tan uniform with optional shorts; worn in tropical climates.
