I'm not sure how much this helps, but for when you start working for Penauille Servisair (to give you our full name since January 2006) I've enclosed the uniform items that you're provided with;
Navy blue skirt or trousers, choice of long or short sleeved white shirts, a navy blue jacket (the current ones have Servisair/GlobeGround branding stitched onto the pockets), a navy blue jumper, a blue and yellow striped neck scarf or tie (again this is Servisair/GlobeGround branded), a winter coat (as you described, it's full length with a hood), a hi-viz jacket, scarf, lanyard and women are provided with handbags.
Rumours are going around that as part of the rebranding from Servisair/GlobeGround to Penauille Servisair, that next year we might be getting a brand new or altered uniform. The problem is the current ones will only be three years old, and as a result the cost may be too much to justify altering the uniform simply because of a name change.
