simple and plain; without any decorations
strict and serious in appearance and behaviour
allowing nothing that gives pleasure; not comfortable
"a stark interior"
"an austere expression"
"a stern face"
"Be systematically ascetic...do...something for no other reason than that you would rather not do it"
"a desert nomad's austere life"
"a spartan diet"
"a spartan existence"
They would be gentle, not austere.
His mask-like face is..grimly remote and austere in death.
