I was playing Dawnguard the other day and i was tired to see Serana always in her old clothes so i tought that i could use a armour from the witcher for her (witcher's armour have the best body and proportion for me) but they were all too colorful for a vampire and i always use Yennefer armour for "dark" characters so i made this retexture of Triss blue outfit from the beautiful:  Witcher 3 Female Armors by zzjay so of course you need his mod for this to work.

The replacer i use for serana in the picture (it's the best for me) is: BVFE Serana and family

Obviously you can use this for your character too ;) I want to be clear this is only a retexture, all the credits goes to the original creators for the base texture and models.

I'm Italian so sorry if i've made some grammar errors :D
