wrapped around her little finger

Ara spent $225 on a prom dress.  $225! 
We went to a consignment shop and the very first dress she tried on was drop dead gorgeous with a drop dead price tag.  Unfortunately none of the other dresses even stood a chance.  And Ara said, "let's get it".  What!  If I went out by myself and dropped that kind of cash on a dress I would have caught hell for it. 
And then we headed to the shoe store and the man picked out a pair of sandals FOR HIMSELF.
I almost started crying. 
It's like he's been abducted and some alien altered his personality.
