We had a thread on this topic recently.
The parish I used to belong to was a Newman Ctr. in a downtown venue. We had several homeless persons who would come in to Mass whose lack of “proper” attire and general unkeptness I found to be not at all annoying. I thought it was wonderful that they were there.
OTOH, we also had an inordinate number of students that were practically undressed - especially in the summer. No bras, butt-crack showing jeans, backless halter tops, minis and short shorts showing more butt. It was offensive. I got tired of hearing, “At least they’re here.”
There is a HUGE difference between dressing in the only clothing available and dressing (?) in what will get you the most noticed.
It’s about respect! If they have no more respect for their Maker than showing off as much as possible to Him who already knows what they’ve “got”, then they should stay home. Would they show up at a job interview undressed to that extent and expect to be hired? I think not. So how much more should they be cognizant of their God and what He thinks of their lack of common sense, taste and regard for Him?
Yes, I’m on a rant here! We’ve gotten to the point where we accept almost anything anymore and make excuses for it. If my parents had ever seen me undressed to the point of young people today, MUCH LESS go into to Church that way (though I’d never have even considered it) I’d have a couple of footprints inbedded in my tail end for all eternity.

(rant over…for now
