Ideally, every single costume option should be available for all toons, irrespective of gender. To genderise any clothing options is contrary to Gene Roddenberry's vision for humanity in the enlightened Star Trek universe. No discrimination based on outward appearance. Infinite diversity in infinite combinations.
I'm so profoundly saddened and disappointed that any Star Trek fan would discriminate and would even go so far as to label a man in a skirt as "perverted".
Hopefully, gender restrictions will be removed at the same time as the forthcoming removal of uniform/off-duty restrictions.
