Do you think someone could tell that your are an artist just by looking at you?

   yes
   no
   I am not an artist

[Yoda]

I don't think I look like an artist .. I am not all that expressive via appearance ..

[FrederikJurk]

I usually just wear black or blue shirts without any print, black pants and sneakers. I could be ANYTHING. I actually like that because people can´t judge me that easily

...a good question for a forum of artists.
However illustrators are not artists.
 Also I remember a tv show where specialists have to discover who in a group is an impostor, trained in a month to look as a professional (chef, artist, cloth designer....). In one episode, a 30 years old electronic technician with no artistic inclinations was trained to make monoprints, he get interesting designer clothes and haircut, trained what and how to say and participated with his artworks to an exhibition together with another three consacrated and veteran artists. Five famous art critics were invited at vernissage to guess who is the impostor; only one guessed right.

I make sure that I always go out wearing a beret and a painters smock, then I go twirl my moustache and hold my thumb up to measure things while drawing them.  That way everyone knows I'm an artiste.  I get thousands of dollars of commissions this way. That way everyone knows I'm an artiste. 

Just kidding,  no, nobody would know.

I usually go for the "Lumberjack" look, flannel shirt, jeans, knit cap
and broadaxe. I prefer to travel incognito. Having to fight off the adoring
crowds and paparazzi can be so... annoying.

I wanted to answer by s joke (also)
However the question is wrong. The real question is:
Do you think that you have to look as an artist?

To wear different clothes than other people? to show originality in clothes?IMO the answer is YES. You have to look different if you are a freelancer and if you want that people to remember you.
The most remembered (for his clothes) author that I know was wearing a jalabiya[Arabian thobe] day and night, summer and winter. And myself  I'm wearing colored ties, that, in the casual wearing Israel, look very "shocking" and different.
But now this is not important; most of my few clients are coming from the sea and the net of internet.

No.

This makes me think of high school days, people were always surprised that I could draw, because I didn't look "weird or artsy."

I'm in the design field now, and don't even look like a designer. I'm pretty sure if I wore all black and cool glasses, they could tell.

[Mirel]

Jenlin, you said:I'm in the design field now, and don't even look like a designer. I'm pretty sure if I wore all black and cool glasses, they could tell.
No ,they will think that you are one of "Men in Black" movie, hunting for aliens:

"You'll dress only in attire specially sanctioned by MiB special services. You'll conform to the identity we give you, eat where we tell you, live where we tell you. From now on you'll have no identifying marks of any kind. You'll not stand out in any way. Your entire image is crafted to leave no lasting memory with anyone you encounter. You're a rumor, recognizable only as deja vu and dismissed just as quickly. You don't exist; you were never even born. Anonymity is your name. Silence your native tongue. You're no longer part of the System. You're above the System. Over it. Beyond it. We're "them." We're "they." We are the Men in Black. "
Kay: We are the best kept secret in the galaxy. We monitor, licence and police all alien activity on the Earth. We're your first, last, and only line of defense. We live in secret, we exist in shadow.
Jay: And we dress in black.
LOL

[sygnin]

Probably not. But I've kinda noticed that you can spot the wannabes quite easily at gallery shows... usually they'll be all dressed up in the way they think creative people ought to be hip and cool. The real working creatives usually look very tired and are grateful to be looking at the art and not having to make changes for once!
