As has been said in previous posts how a skirt or pair of trousers look depends ona number of factors including the height & shape of the girl,material they are made from.etc,etc Dont you think that when cabin crew are receiving their uniforms they should be issued with 2 skirts and 2 pairs of trousers and let it be up to the Individual CC member to decide which she would like to wear depending on time of year/weather conditions/destination etc. I personally prefer to see a nice smart pair of trousers worn along with Heels and Tights on a girl as i think it looks very professional and is quite practical in colder climates.
