I bought the DLC bundle right at the start of my playthrough. So I equipped them almost from the get go.

I've got to say I really like the outfits as an aesthetic change. Since I bought the bundle I didn't even pay attention to their stand alone price, but it was a nice change from the original outfits which I saw for the whole playthrough I did when the game came out.

I think Serahs Style and Steel outfit is available for free from the xbox and PSN store for those who don't want to drop the extra bucks
