Hey folks! I believed to stumbled upon into this post searching on how or when to find the cheerleader dress of your beloved sister .lol
Follow the instructions below and you''ll find it!
First you have to go outside of your room and take a look at the ceiling.
Yep, the attic! it''s clickable though, you cannot open it yet because you have to find a stool and the key (because it was locked)
Go to your house garage
Now find the stool and click it
Get back into your house using the front door
From the front door, you will see the KEY to happiness .lol
Now, after obtaining the key and stool, go upstairs and click the attic
Inside the attic, you will see the purple attire
Yep, that was your sister''s cheerleader outfit!
Hope this post helps :)
