From Detective Comics No. 410:
No super-deep points to make here, I just wanted to post this ridiculous picture, from a time when Batgirl was an accepted part of the Batman Family, yet was primarily concerned with catching lonely-hearts killers or investigating crooked wig manufacturers or, as here, protecting a top fashion model whose life was in danger from a clothing manufacturer that stood to lose millions if she endorsed the wrong length dress for the coming season.
Dames, eh? Who can figure 'em?
