The uniform would carry “retired” it is a perfectly normal thing in the military world.
No it's not. You are confusing two different things. When an officer retires from the Armed Forces, under normal circumstances he or she is permitted to retain the rank they held on the date of their retirement, and is advised not to dispose of all their dress uniform, in case (for example) of a recall to duty. They are issued with a set of instructions detailing specific "Occasions when uniform may be worn", and "Occasions when uniform may not be worn". Retired officers above a certain rank (it used to be Captain RN/Colonel/Group Captain) are allowed to wear uniform at their own discretion. When a retired officer wears uniform, there is nothing whatsoever on that uniform to indicate that the wearer is retired: no badge; no embroidery; no placard worn around the neck..
The "retired" bit relates not to the uniform, but to the individual's post-nominals. Thus, a retired RAF officer might have a letterhead saying, "Air Commodore P Prune, AFC, RAF (rtd) - where the (rtd) indicates that P Prune is no longer serving. I understand, however, that this may be changing, and that retired officers will be under no obligation to use the (rtd) addition to their post nominals.
When wearing uniform, wearing one's medals depends on the occasion, and is generally specified by the sponsor of the event, or (lacking that) is a matter for the officer's own experience and judgement. Out of uniform, the wearing of medals is a matter entirely for the individual's own taste and judgement.
