Does designer make you fashionable? probably. is fashionable a good thing? certianly not always! it is more important to be well dressed, which can be a completley different thing!
That is a very good point. I would rather be stylish and elegant than fashionable. Being in fashion doesn't interest me.
As for the actual question. First of all, what do we mean by "designer"? Do we mean huge luxury good companies like Chanel and Dior, who's logo brings instant status (or so some think)? There are people who are fashion designers but are not as "fashionable" or logo-ed, like Ann Demeulemeester and a lot of indie designers who do well. I would certainly think that kind of clothes can make someone stylish, but if we mean does slathering yourself with logos and it-products make you looks stylish, then not.
If you do have a taste and know what suits you, it is good to be able to afford pricier items too. It is too difficult to make your fashion dreams come true if you don't have money. But money can never buy elegance or style. If the person has a good idea, money can help her bring out the idea of elegance she/he already possesses. But if you think the price of your clothes is synonymous with elegance or style, then you are going wrong. Look at all the celebs, they have tons of money and still 99,9% of them dress like they have no idea of elegance or style. Sure, they are covered with noticeable designer items of the season, but are they stylish? No. Are they fashionable? Probably yes.
Elegance and style are not up to money, they are up to your thoughts, manners, creativity and personality. Fashionability is up to clothes. I guess you can these days achieve fashionability by shopping at H&M though, because they seem to copy every trend. So no, to be fashionable you don't need designer, but it will certainly help. It can make you fashionable, just bring style.com's "Season's It-items"-list with you to the closest Chanel store and ta-dah, you will be fashionable. Not necessarily stylish or elegant though.
