Hey I kinda noticed that pride Freddy's outfit reminds me of a consort or a concubine outfit but I could be wrong (which are really pretty)
They are both very pretty, though that's not his main inspiration. Pride Freddy's outfit is actually based on Greek/Roman statues, specifically of their gods. It's to represent how he feels superior, and/or godly.
(Note: I plan to change Pride's reference a little, but the look/inspirations will stay the same).
But, he's also meant to look alluring, to show how an ego or superiority can quickly go downhill, even if it looks harmless.
Another reason Freddy has a Greek/Roman statue motif is that the deadly sin pride is elevating oneself above god and others. Which further drives this point, since he sees himself as higher than god and others.
But I can totally see where you got concubine since I wanted to make him look alluring and kinda hot (In kinda a "hot rich supermodel from the movies" way if that makes sense), also wanted him to be like "I'm mean, but I'm also pretty, so it doesn't count" type of person.
He's like a beautiful poison, or like a rose. So beautiful you forget it's thorns.
