I'll take a boobie burn over the case that lodged between my glasses and my eye lid a couple of years ago, raising a blister on my eye lid. That's a very peculiar feeling when you open your eye...
Having experienced both, I'm not sure I agree. They both suck.
The problem with hot brass
isn't that it leaves a blister (though that's certainly both annoying and painful). The problem is that people do dangerous things when startled by it: they jump frantically around with the muzzle waving in all sorts of stupid directions, their hands -- including the trigger fingers -- suddenly clench in surprise or pain, they start reaching into their clothing without getting the gun out of their hands first ... you name it.
For that reason, YES, wear a high necked shirt if you're female. And you need to know that a button-down shirt catches just as much brass as a scoop neck shirt, too. Really, a tee shirt in summer and a turtleneck in winter are almost mandatory if you want to avoid having to do the hot brass dance.
Also, um. If you like crop-cut shirts and low-rise jeans, if the brass goes over your shoulder and rolls down your back, guess where it's gonna lodge? Wear a shirt long enough to prevent that, k?
Next up: that eyelid burn can (and should!) be prevented by wearing glasses that have side shields
AND wearing a ball cap at the same time. The side shields protect against brass coming in from the sides (duhr!) and the hat protects against brass dropping behind the glasses from above.
And if a piece of hot brass
does surprise you, for Pete's sake get the gun out of your hand before you do the hot-brass dance. Everyone on the range will thank you...

PS That hot-brass dance, by the way, is called either the Bra-zillian Line Dance, or the Cha-Cha.
