Let me explanin all this mess here.I also designed and got all the pieces and I wanted to uprgade them but...As you know there are needed some special girft(priam boxes) and expect them you need to (e.x. for dress or hair ) redesign the dress 2 more times !!! SO YOU SHOULD DESING IT 3 TIMES !! This is so curel TT You need to buy again 4 purple things to create 1 new dress and then 4 more to create and 1 to reach 3.But 1 of those puprle things is 45 gems and in total 8 purple things ×45=360 gems only to uprgade the dress and 360 for the hair =720 gems only for the purple things !
