Look at yourself and make yourself beautiful
You've been waiting for this guy to ask you out for the first date and when it finally happened you start to panic. You don't know what to wear, you have no idea how to behave. So let me tell you: just breathe and I'll help you out.
First of all, you need to remember to be punctual. Show up no later than 15 minutes after the time you set up the meeting. Being late means disrespecting the other person and you don't want your date to think this way about you.
While thinking about what you're going to wear, you need to know the place you're going to. A dress and stilettos won't be a good option for a park or a rock concert. If he arranged the meeting at some fancy restaurant or an opera, choosing a nice dress will be appreciated by your man and he will notice right away your elegancy and chicness. The most important thing is that you will feel comfortable and you will able to move freely. Don't look at the most fashionable clothes or colors, look at yourself and make yourself beautiful, whether it is an A-dress, a pencil skirt or a pair of jeans. The shoes are important as well, because if your feet will hurt you, it may damage your mood through this special moment you'll have together and you don't want this. I would say to be careful about the length of your skirt or dress (not to short) and exposure of your cleavage, because it may make inappropriate impression.
If it comes to the conversation, you can think of some topics you want to talk about before the meeting. Think of the things you are comfortable talking about. Remember to listen to your date, what he wants to tell you and just be natural. Also, don't talk too much, because some women in order to hide their stress, talk a lot.
Sometimes, it occurs that the date isn't going so well, so you need to be prepared for a good excuse where your date won't be insulted or too suspected, like a phone call from your best friend, which you'll set up earlier.
All in all, put a smile on your face and everything will go well!
