Alph2z, the "blonde" flight attendant (as you put it) did not refuse to wear her uniform.
If you watched the programme, she said that she didn't feel ready to wear it yet. Doreen Welsh was the most seriously injured on that aircraft, she, (and the 154 others) has been through a traumatic experience. I for one don't blame her one bit for saying that she doesn't feel ready to wear her uniform yet.
I suppose a comparison can be made to having a car crash. Some people can get straight into another car and drive again. Others have to steel themselves before getting back behind the wheel, some may take a while before they can do it, and there are some who may feel that they can never drive again.
Cut the lady some slack and let her recover in her own time and in her own way.
