To be rather honest, nothing t́́o̕͡ơ͘ e҉̸x͞t͘͟͟ra҉v͜a̧͜g̸a͡n͜t͟. I have heard these events require black tie at the very least and my uniform does not fit that requirement.
If it wouldn't be asking too much, I would also ̛͠͡ ́͢͝ ̢ be grateful if you would be able to assist with hiding the wound on my neck. My service uniform covers it well, but anything with a shorter collar would not.
