Is it okay to think my aunt's wardrobe is too much?
Is there is something dramatic about how she styles?
Her choice of clothes is too weird and she looks like a clown
Maybe you could offer her some fashion advice in a kind way that would be constructive for her.
Older people that can't style should be beaten and maybe I should teach my aunt a lesson like that.
Beating your aunt will not teach her anything and would be very hurtful to her. Sometimes older people lose touch with their style and are left behind with older clothes. Offer to go shopping with her instead and help her pick out some up to date clothes that are a good fit for her. You can do this.
