I am the only person who thinks her new outfits suck? (personal opinion)
Its just this ones dosen't feel like light's stile. She were more of action woman than a sex appeal stript.
I mean her FFXIII costume was fu*king great. THe one from FFXIII-2 was mind-blowning. And now they get this? Shadow Dust is the only one that pass. If her starting outfit's leg capes were removed and clothing in her back were added in could be nice.
Considering that only 3 of 20+ outfits (that with DLCs will very probably easily surpass 30) have been revealed, i don't think you should worry too much.
Personally i like the 3 seen so far but, as you said, it's just a matter of personal taste, i'm sure that between all those outfits there will be some that i'll love and some that i can't even look at, it's normal.
Keep in mind that you can also recolour everything, so some of the dresses that in their "original colours" you don't like, you may like them more if you change it (For example i plan to see how the green costume will look grey/black, imo it could be way cooler, or at least more fit for my taste) .
