I’m trying to decide if the word topless is being used incorrectly?
Traditionally, topless meant exposed female breasts. They could be partially covered by hands or objects. But topless implied the front side of the person.
Lately, shots from the back are labeled topless. 
Example, completely safe for work of a tat on a lady’s back.
We have no idea if her front has some covering.
Did the meaning of the word change? Is this use of the word just clickbait?
Oh man, when I saw that headline, I couldn’t wait to get home to see the photo. It’s just her back? What a rip off. That’s not topless.
“Topless” means, no clothing from the waist up. Applies regardless of gender.
Yes, it means (partial) nudity is involved, as it is in the picture under discussion. Berry is not wearing anything on her top, therefore she can be accurately described as both “topless” and as “partially nude” (she’s not completely nude because she’s still wearing a skirt).
“topless” means the writer consciously or unconsciously promotes the notion that a person’s upper torso should be covered up. It’s generally sex-specific (women’s torso, not men’s). Every time I see it in print I visualize Beavis and Butthead drooling imbecilically.
Yeah, it’s really weird seeing topless used for men.
I don’t consider a guy without a shirt topless. I mow my yard without a shirt.
I don’t think it gives the neighbors a thrill. 
Though technically topless means “without clothes on the upper half of the body”, my mind instantly goes to “woman with with no top, breasts exposed”, which is exactly what the writers of the click bait were betting on.
I would call that ‘shirtless’, although thinking about it, I’m not keen on the gender differentiation – certainly the idea that it’s ok for men but not for women
So you perceive topless as being erotic?
It can be. It depends on the situation. Sometimes it’s just a lady without her shirt.
I usually think of the neon signs at Clubs in Vegas.
Agree.
As good an excuse as any to post this fun song.
It’s a sure way to get an R rating in the US.
Is this a serious question?
ETA: Wiki seems to agree it refers to a woman without a shirt with breasts exposed. I’d link, but it’s NSFW.
This exactly.
To me, “topless” implies a female, as men don’t wear “tops” they wear “shirts,” but maybe that’s just me.
“Shirtless” would be ambiguous.
