Which in turn seems to come from trying to adress complaints that have been voiced around the internet for a while (wether by a small loud group or a larger reasonable group is difficult to confirm), not only by female readers or fans (again hard to pinpoint if it's actual buyers or just people wanting to complain about something they don't even consume) but also some male readers/fans about said kind of classic costumes and wishing for more reasonable alternatives
Though these complaints and what alternatives these people want, can largely vary. Some want total covering or androgyn costumes for a sort of leveled playing field between male and female characters, while others simply want the classic costumes redesigned into a more semi-practical look.
Like just wanting high heels gone from costumes, or some kind of increased fabric coverage around arms and legs, or power armor wearing heroines to not have feminine shaped power armors.
Most female super hero comic consumers i've seen (so take with a grain of salt), seem to belong to the later group, who simply want their favorit female heros in costumes which are both stylish, yet at least practical looking. Though there are also female readers who had zero problem with the classic costumes and their fan service aspects and are actualy annoyed by the redesign trend just as much as some male readers are.
Also several seem to find the notion of putting up a super hero fashion show to draw more of them in condescending. Go figure.
Though there is also another opinion on what could have started the trend of redesigns and that is cosplay and movies. Basicly pre-emptive redesigning comic costumes into more wearable looks so people can dress up as the characters easier, both at conventions and for movie filming.
Either way, there is a trend for less revealing costumes, what ever it harms the sales or has no effect isn't easy to confirm however.
As for Emma Frost. She gets a free pass, because a core part of her character in the eyes of many writers, artists and readers seems to have become that she always wears skimpy form fitting or revealing outfits. It's expected from the character by now.
With the reason regulary brought up being that she is a moraly grey character and former villain, so it's no problem for her to be more "lose" about her dress code.
