Yes, that would be for service dress, and full regimentals would be a whole different matter. But I believe expectations in war-time were different regarding that.

Regimental tailors still often advertise special rates and terms for cadets and junior officers, and some, like Gieves & Hawkes, provide a special kind of storage service for full dress uniforms.

It used to be that the men had the cost of their uniforms and equipment stopped from their pay, but by the time of the Great War, when it was about a shilling a day (5p) that had come to an end.

In the days when the commanding officer could add to, or change, elements of the uniform arbitrarily or on a fancy, the poor individuals of the Other Ranks were perpetually in debt to their regiment. The only benefit was when the individual left the service, and his gear left with him.

My father's uncle who served in the Seaforths at the same time as Collins, gave his kilt to his youngest sister for her to make into a skirt.
