Or alternatively just wear what you want and tell the offending member of a "corps" that it is a Regimental thing and if it is any of his business, then it is "Dress 14a, Summer - Stables Undress" and to bog off and worry about things that concern them, then chase 'em out of the room with your crop and set your gun dog on them
No, you wear the pattern of shoe dictated by your regiment. For most this will be the issued brown shoes you will leave Sandhurst with, as you (like I) are in the cavalry this will probably be something slightly different, but certainly not your best pair of brown brogues that you have worn since school. With (I think) one exception, regiments also require you to bull your shoes. Most cavalry regiments will also permit you to wear a pair of brush polished brown Cav/Jodhpur boots in lieu of brown shoes when in barrack dress and not on parade.
Speak to your Adjt who is responsible for subalterns' dress and turnout. You will find yourself with extras if you get it wrong or flout the rules.
If I were any more ruggedly handsome I wouldn't have the strngth to fight the ladies off. I have enough bother as it is & if I succumbed MrsPlume wouldn't damage me physically, but she'd up sticks with MasterPlume & I would probably jump under a train.
I love the joke of the Samrt Turnout range & feel positively Wodehousian in my Old School/Regimental/Corps socks. I have asked my Club if they will get some, but I think the Secretary thought I was joking as he hasn't answered my letter. Particularly fond at the moment of these to brighten up drab Office attire, they're by chance in my Sevens team's colours:
Anyway, back OT when I joined the Skins the choices with barrack dress were black Oxfords or George boots with Barrack Dress (or Working Dress as we called it IIRC) and we were encouraged to wear maroon socks. I worked with an RDG chap just before I left & it appeared that in addition to the Oxfords & George Boots Jodphur Boots in black & brown were also worn as well as a whole load of others. NO wonder Young Officers are broke!
