Well, very often you feel too greedy to spend your precious money on a designer, so you think that you are a designer yourself and you start the redecoration of the entire flat or house just picking up things that suit your taste...well, how about their mutual match? Two things might be good separately but when combined...So, what I think if you don't want to lose money, at least read some sites and gather information about latest trends. I personally consulted when I was in the process of redecorating my bathroom. So now it looks more or less stylish, don't say it's the one where kings take showers, but pretty decent you know.
