Why are clothing departments for women bigger in the real world? The conventional thinking is that it's because women like to buy clothes. It's a massive generalisation and one which self-propogates.
In FFXIV, however, there is no rule saying that girls who like guys, guys who like guys, girls who like girls or any other configuration of gender/preference necessarily matches their character's gender. Their character gender is a completely arbitrary flag (especially in the case of Lalafell, who use the exact same model for both genders anyway and should never be genderlocked out of any gear ever). Whether I'm male or female in real life has no relationship whatsoever to my desire to dress up in FFXIV. The FF series has always dressed both male and female characters beautifully in a mix of masculine and feminine clothing, and attracted people of all preferences and tastes as a result. It's practically one of the hallmarks of the series.
An in-game glamour bias appearing during ARR makes no sense commercially, because they believed at the time (by their own admission) that the gender split was equal if not in favour of male characters, and they weren't making extra money from the in-game items (any argument that it might get more theoretical sign-ups from female characters could be countered by the amount of money lost dealing with people like myself who end up ragequitting and swearing off all future S-E products). It would definitely have taken more man hours to adapt the Best Man's Suit to the female form than to set the bunny ears to work on all genders, since they don't even need remodelling - just positioning slightly, and the Japanese fans were specifically promised that it would be done 'as a priority' back in 2015, which to me shows intent to either delibrately mislead all of the players with male characters or some serious failure to prioritise. However, either way it's not something you say when your intention is to deliberately favour female characters. If that were the case, I would have had infinitely more respect for Yoshida if he had just said 'no bunny ears, all female characters are played by women and only women wear clothes IRL' back then rather than leading me on for years by pretending to understand the issue.
A cash shop glamour bias appearing after the outcry over the in-game bias also makes no sense to me, because they cannot possibly have enough data to compare how worthwhile it is when they have been phoning the male options in for so long. I never bought any of the male-only cash shop glamours because they didn't arrive until after I was embroiled in this problem of being treated like a second class customer; I didn't buy Aymeric's (which I actively like) because to do so would have accepted the insult of S-E releasing his hairstyle as a unisex item against all of their own supposed principles. I buy - well, bought, not spending a single cent there any more - tons of other unisex and fluff items on the cash shop and as merchandise tie-ins, but gender locked items don't work in the favour of anyone with a male character. And since other people openly fantasia to gain access to be better glamours, any stats from the cash shop broken down by character gender are questionable.
Will people spend more on better items? Yes. That is absolutely unquestionable. Do female glamours always have to look better than male ones? I don't think they do. The women (and gentlemen of discerning taste) who shop in those vast womens clothing departments in the real world could appreciate finely tailored menswear too, and unlike the real world a game lets them actually wear it and have it fit them properly no matter what their shape. The designers are capable of this. The High House Justaucorps looks just as good as the Bustle. The Songbird outfits for both genders look great. The South Seas Talisman is a very acceptable masculine alternative to the bikini top it replaces. If we didn't know they were capable of good work, we'd believe them more readily when they suddenly act as though fair treatment is impossible. If it really is that hard to make a bunny suit or bustier fit the male form, I am happy to break out Blender and adapt some using nothing but existing in-game assets if they want help. They have already modelled all of the parts I'd need to do it.
If the game has changed from the one I first joined, and S-E is no longer intending on catering for 'all of the players' as everyone is suggesting, they need to be much more clear about this than then have been historically. It's not fair to mislead us with platitudes and broken promises.
