Give her some money to buy new clothing and to go to the salon for whatever she wants- highlighting, nails, massage.
I've told her often to not worry about money. A $2000 flight is a lot different, especially when it really is a separation she wanted. I wish she cared about her clothes, etc. I've tried hinting, "Boxing day sales are super for clothes" type stuff. I've tried not to insult her clothing, but she has so many nice things she just won't wear. Instead, she wears stuff from the 80s and 90s she found at a used clothing sale.
Someone suggested to me that a makeover type thing might perk things up, but I don't dare hint to that! I'm in enough trouble as it is~
