This is something that's always bugged me about the original Batwoman's costume: WHY the HECK is it yellow and red? It's primarily yellow with red accents. WHY, WHY, WHY? The design itself is batlike enough, but the colors certainly don't say Creature of the Night. If idea was that Kathy (Batwoman) Kane was trying to emulate Batman's look, why on earth did she have costume colors (not to mention the elf boots and gloves) more in line with Robin's original look than with Batman's?
The costume for Batwoman's sidekick/niece, the original Batgirl (Betty Kane), wasn't any better. Not only did Batgirl wear a skirt (Wonder Woman discovered a LONG time ago that skirts just aren't practical for bashing in badguys' heads), the primary color of HER costume was red with green accents. Again, more in line with Robin's look than with Batman's.
I don't get it. I just don't get it.
