Bringing her over once you're ready is a little hard. Guys that live with parents are going to make her feel uncomfortable if she has to go over. It's already awkward with you as an individual.
Now remember this. Have your place ready for a lady. This doesn't mean you need some insane "hip hop star" love pad with the potion of seduction enveloping every little item and cranny. What this means is you need your place presentable at every moment. Do you have old socks or pizza boxes hanging around? Would you bring a girl back to your pad, given its current state? If the answer is no, you need to work on that spatial hygiene. Now you don't need to be able to eat off the floor, but you do need your bathroom to not repel with its smell, your floor to be visible, and your general organization to be a cut above other guys she's been with.
Go too far and you look a bit like a neat freak but that's far better than looking like a slob. The worst stereotype about neat men is they aren't interested in ladies and hopefully, you'll be able to prove to your targeted woman that isn't true within a few moments. However, if you manage to elicit a lady's disgust factor (everyone has theirs, although generally, the closer you get to the toilet, the higher the risk) you can ruin a night's worth of work. So, take the time. Keep your place clean. Always. You never know when opportunity will present itself. Be a boy scout and be ready. If you have a small place it's a bit easier. Hopefully this girl is not so materialistic but just wants you for who you are.
Be clean in every way take care of your own hygiene. You'd be surprised how often bad breath is the date breaker. In fact, an offending smell is one of the most unattractive things known to humanity. Chances are at some time or other in your own past it ended what would have been a beneficial connection. So, considering we lose any sense or our own scent very quickly, it's best to play it safe. Assume you smell awful, and take the necessary precautions. Have a bath. Bring along some sort of breath saver. If you sweat, wash, and if you can't wash, deodorize. Aftershave, used in moderation can be a Godsend. Basically don't have any reeking smell in the house or with yourself. Being a woman she understands you're a "guy" and that will happen but she can't stand a guy not bothering to make some effort to help himself.
As far as fashion goes, you don't need to be straight off a Paris runway. In fact, unless you have talent in this area, simple is the best way to keep it. A nice pair of slacks and a plain black shirt is plenty as long as you wear it with confidence. Flashier things can get some attention but before putting them on you want to be sure it isn't the wrong kind. Simple is fine. Really. Just look clean and fresh and you'll have no problems.
Create the attraction, be playful and fun and extend your time. This can mean getting a number or email, shifting your locale, or any of a million other things. The main purpose here is not to bring a woman to bed, but merely to attract her. All you need be concerned with is getting her interested enough that she wants to spend more time with you. Best to do it with your relaxed and playful attitude, but if time is short, just get a number with little more than confident politeness. Don't worry about what comes later. Just get her interested in you to begin. Lead her in some direction in your life. This can happen at the same time, or at a later date.
If things are going well at this point you can shift quickly into physical contact, but at the least you should start introducing familiarities like hand holding and relaxed touching. You're building to a later point here, so don't try to take more than is being offered. You'll get turned down and likely lose a number of points and digging yourself into a deep hole. Just concentrate on establishing and strengthening your connection here. Again, that should be your only priority. If you really want to sleep with this girl, fine. That comes later. Stay focused on your contact with the lady. The rest will follow successfully. You got to first make sure the lady is into you. What do you do then? BRING HER HOME.
Her place or yours. Whichever works with the seed you've created earlier. Once you get her there, don't rush things. She's already basically said she's interested in going further, but push too fast or you'll turn her off and undo all the good you did earlier. Instead, take your time here. In fact, if you wait just a little bit longer than she's comfortable with, or play hard to get yourself, that's even more powerful. Turn up the heat all you need now is the transition to physical connection. If she starts heating up as well then you're on your way (you lucky dog) for some hot sex that night. You can probably tell because she'll be moaning or making some sexual sounds at every touch. Take that as calls from her to come in and that it's alright with her.
Bar advice. Bringing her over can be a job all in itself but the reward is if she stays the night(sex and all) you can blame the mess in the house on her as well.
