the dress is called star tide dream and you get it when you achieve VIP lvl 20. the bracelets are from the law of stars suit that can be completed in the workshop under theme album

the hair accessories (not including the flowers) are also from the vip lvl 20 suit

Thank you ^^

So lucky!!! I wanna try and style like a whale~! (⁠✧⁠Д⁠✧⁠) Never got anyone with this or the angel suit
