I got bored so I calculated how many diamonds I've spent as of now since playing in July:
Wings~119,425 diamonds
Skirts~100,500 diamonds
Heels~137,500 diamonds
Mermaid Tails~10,000 diamonds
Accessories~165,050 diamonds
Also an estimate on how much I've spent on food~1,275 diamonds
And that adds up to a total of about 478,925 Diamonds that I've spent in RH
Oof thats a lot XD
