Olive Drab Bush Dress Shirt, 1950/60s. It was worn under the bush jacket. From 1946 until 1967, the Canadian Army wore for summer dress, the green denim uniform called Bush Dress. Bush Dress replaced the Khaki Drill uniform but Bush Dress had several significant differences. It had a closed collar which was almost always worn open. It could be worn with a shirt and tie when used as a parade uniform. It had a 5 button front closure. A cloth waist belt was also worn with this uniform in the absence of other types of belts (i.e. if for a parade belt with bayonet and frog was worn or webbing equipment, the cloth belt would not be worn). It had two breast pockets, box pleated, with scalloped flaps secured by buttons and two flapped bellows-type hip pockets. The vented cuffs were secured by a visible button. There was no Scottish/Highland Pattern as these jackets were intended to be worn with denim bush trousers and not with the kilt or trews.
