Ladies clothes (Howell, MI)

I'm getting ready to start going to court with my son for visitation rights and I need help with dress clothes
I have nothing decent to wear.

Black and gray xl blazer's

A couple of white shirts maybe long sleeves would look better

Pants to match with the blazer's

Size I'm not sure if have a 39 waist and I'm 5 feet tall i can fix the pants that's no problem.

I really appreciate any help .

We are going to probably start going to court this month.
