1. Conceited

Confidence can make you appear incredibly attractive. However, being conceited will take that attractiveness away. It's healthy for you to be happy when you look in the mirror. It's even healthy for you to be proud of affording the newest iPhone. However, if you go around bragging about your looks and material items while putting down the people who aren't as fortunate as you, then you're going to be considered unattractive.

2. Rude

When you get excited over something, it's easy to interrupt the person you're talking to. However, if you make it a habit of talking over others, ignoring what they have to say, and giving flat-out rude remarks, then you're going to appear unattractive. Relationships and friendship are all about communication, so if you don't care what they have to say, there's no reason for them to stay in your life.

3. A Liar

If you constantly lie, cheat, and steal, people are going to be afraid to be around you. They'll never know when they can trust that what you're saying is true. If they can't believe a word that comes out of your mouth, then why would they spend time with you? Your looks aren't going to make them stick around when your words keep pushing them away.

4. Temperamental

If you threaten to break up with your boyfriend after he looks at another girl, or if you flip out when a waiter gets your order wrong, no one will want to spend time with you. Things go wrong in life. If every little thing sets you off, then you'll appear unattractive. It's sexy to go with the flow.

5. Narrow-Minded

In this day and age, one of the most unattractive qualities is narrow-mindedness. If you refuse to associate with someone outside of your gender, race, sexuality, or social circle, then you aren't going to be considered attractive anymore. In 2015, open-mindedness is in.

6. Selfish

If you never share your food with others and don't care about who you step on to get to the top of your career, you might be happy. However, you'll also be alone. Even though it's healthy to be selfish in certain situations, you won't keep any friends or boyfriends if you only care about yourself.

7. Messy

If your clothes are always dirty, no one will notice how pretty your dress is. If food is always stuck in your teeth, no one will realize that you have a beautiful smile. Messiness can make the prettiest person appear unattractive.

Not only will these traits make you appear unattractive, but they'll also make you feel bad about yourself. That's why you should always strive to be a nice, upstanding citizen. Which personality trait do you consider to be the most unflattering thing in the world?
