short items to wear for older bride of the wedding

Dear prom dress stores,
I’m sorry I’m not a size 6 but I would really appreciate if you had more then 3 dresses in my size,a plus-size... I’m not the only chubby girl that wants to enjoy prom this year so how about you advertise some dresses that I don’t have to be a six 6 under to squeeze into. I’m not in love with my body and looking for a dress, when it should bring me joy, makes me hate myself little more. short items to wear for older bride of the wedding
