This is a small MyTake of things I have personally experienced that make women more attracted to you. Granted, this assumes the particular woman or women have a little crush on you in the first place, but whatevs.
(1.) KIDDIE PHOTOS!
You know what women like? Kids.
You know what you were once? A kid.
So go call your mom and actually ask how she's doing, and then ask her to give you your baby and kid photos.
Women love to see that sh*t. Seriously. My ex-girlfriend is my ex, BUT STILL LOVES MY KID PHOTOS BECAUSE I WAS CUTE AND NOT SOME HAIRY MONSTER.
It also shows you're not embarrassed. There's bound to be a naked photo or two of you in that scrap book (I know I had a few), and she's going to talk about your chubby cheeks and shit. If you're willing to show her you as a kid that means a lot to her.
(2.) Speaking of kids, play with them.
Wanna show that you're not only a kind guy but also a great father figure? Play with kids! Kids love when someone bigger will play tag and hide & seek with them. They can be your family's kids, a neighbor's kids, maybe you become a camp counselor, etc. If your crush isn't there to witness, there's Snapchat for that.
This is also beneficial to you because not only will it teach you how to play with kids, but you'll also have a fun time just not being an adult for a while.
If you don't have kids, dogs are a good substitute.
(3.) Don't be afraid to have "unmanly" drinks.
For some reason, men (actually frat bros) have made a rule on what is and isn't acceptable for a man to drink. The rule is: The better the drink tastes, the less manly you are for drinking it.
You are "feminine" and "gay" for having drinks that taste good. So if you're a man, you shouldn't drink Wine (whether red or white, but mostly white), Piña Coladas (or any cocktail really), Orchid or Tea based drinks, etc. As a man, you're only supposed to drink pure shots of liquor or just beer.
Don't be afraid to try something different. Now, there are some women out there that will probably laugh at you for ordering a Cosmopolitan, so maybeee don't try all the red looking cocktails first. However, if you show up to a Night Club or Cocktail Party and *GASP!* have some Chardonnay, chances are you might fit well in with the ladies. They'll respect you for being comfortable with the fact you aren't afraid of drinking "unmanly" varieties of flavored Ethanol, and you'll probably just be allowed to just join in with the group while the rest of the bros are busy trying to dance with girls that aren't interested while they hold a bottle of Whiskey. Be an adult and don't be worried about what immature people judge you on.
(4.) Either work with something hand-wise or show your knowledge practically.
This is a little pneumatic air engine that I machined and assembled myself. Air goes in a little hole, pushes the piston down, turning the crank, and turning that massive flywheel you see at the end. It's simple, but girls think it's awesome I handbuilt everything but the screws holding it together. I also have a knack for fixing and working on cars. So I have that component of handy work.
However, hand skills aren't the only think that women like to see a guy have. Women also like it when you're intelligent and knowledge and can use those brain skills in a practical way. In my experience girls enjoy it when you help teach them how to do something new. One girl I almost dated (until I met my ex) was really attracted to me because I taught her how to do chemistry in my study group. Little things like that go a long way.
(5.) Show that you are in fact, an adult.
There are some things that I've noticed young men tend to suck at (Even me on rare occasions), that are necessary for adult life. These include:
Laundry, Cleaning, buying good food, having spare items, making sure to regularly change your sheets, and using money in at least a semi-decent way.
I had to teach my old roommate how to put on a fitted sheet, after he finally decided to wash it for the first time in several weeks (ew). I'm not saying you should leave high school knowing how to cook (I can still only do basic stuff) or have an emergency fund, but for Christ's sake please know how to change your sheets. Women like to walk into your place and see it clean, well organized and spare toilet paper in the bathroom closet.
Have at least some fruit, yogurt, and non-premade foodstuffs in your fridge in addition to your booze. You don't need a lot of money but don't be an idiot with it either. I can proudly say at 20 I have a credit score of 730. That's much better than many guys my age or older. If women can see you know how to take care of yourself and live like a proper adult, they're going to take you much more seriously than your average bro that doesn't know how to do laundry.
Alright everyone, I'm out. Hope you enjoyed!
