Just tap on the dress up stuff.If they come in some random place,do drag them to the place you want.The arrow has been there in 2 directions left and right.Tap them to see the previous and next backdrop.They are atleast 18 dress up things to chose from.There are 3 people,one in the front,one in the middle and one in the last.Chose which sprite do you want to dress up.If all the clothes are out of there arrangement press the green flag.You can also dress all of them one by one!Thank you!
I learnt it myself. PLEASE READ INSTRUCTIONS ABOVE.
