Raw training routine

I've been trying to find a powerlifting routine, or atleast guidelines to create routine which doesn't revolve around using shirts or suits to lift in. I've tried a WSB routine and a 3x3 routine. Both without using a shirt or a suit. I wasn't very happy with the results I got from either. Could anyone suggest a routine or guidelines for one if I'm only interested in doing all lifts raw? Thanks.

Here's what I do:

SUN

deadlift 1x3
bent rows 2x5

TUES

bench 1x3
incline 1x3
military press 1x5

THURS

squat 1x3
zercher box squats 1x5
