Angel Dress does not exsist period. I checked in DAOLA v1.2 for WLO 3.0 aswell as melone. I searched under the said lvl (30) and found nothing.
Then I searched for any lvl and still found nothing. Then I went to look further 1 by 1, took me 10 minutes XD. And still found nothing. So I googled it. And all it showed me was this topic page rofl. So I think its mor than welcommed to delete that item.
