But it can buy you a whole load of jewelry and furs.
Casino (1995) is one of those classic mobster films, in which the characters have such a ridiculous amount of money that they have nothing to do except wear extravagant clothing (well, that and killing people).
Ginger (a.k.a. Sharon Stone) is pretty much obliged by fashion law to be stylish; a) she's from Las Vegas, b) she's a hustler, and c) she's the wife of a gangster (see Elvira). Though being the wife of a gangster would seem to be the most influential factor in Ginger's style choices, I would say it has more to do with location.
Can you imagine anyone, in the '70s and '80s, who is wealthy and from Las Vegas and doesn't sparkle vibrantly? I don't think so.
As much as I love Ginger's style, it does become too dishevelled when she becomes a druggie and goes back to her loser boyfriend.
There's a lesson to be learned here: in the long run, money can't buy you style and panache (am I quoting the lyrics to a certain Real Housewife's song?)
