If they had made them all unisex other than Minfilia's, it would be worsening the existing problem where those with female characters are always being given special treatment. From what I understand, they were originally planning on releasing just Minfilia's outfit then adding the rest at a later date. People (such as myself) were rather disgruntled that this would mean that 3.1 would bring an additional two female-exclusive outfits with nothing for the guys, and S-E's response was to bring forward the release date of the male Scion outfits. For once they resisted the temptation to make them all wearable by female characters with only a few available to male characters, and thus we are now in this position while they continue to review the underlying problem with the design team.
I would hope that when the day comes that they have either figured out how to adapt Minfilia's outfit for our lanky, masculine bodies or picked out a single male-only equivalent for the cash shop (Aymeric, please), they'll consider unlocking all of the other Scion costumes for both genders.
