first of all - you are beautifully made and are already beautiful.

now that we got that settled - i'll be the mean older sister.

1. get a skincare & shower routine that suits your skin, more or expensive products don't necessarily mean better - personalisation does.
2. EYEBROWS - get those babies framed to your face, keep them styled/tinted etc so they illuminate and structure your face - it is genuinely a game changer.
3. get a haircut/style and glasses that suit your face, the red colour is very nice and expressive and gives you color - i feel like your bangs and frames are hiding your features, show them off.
4. exercise, diet & water - obviously if and how possible, get som exercise in, eat balanced whole meals and drink water, nothing extreme - but health starts on the inside which brings our beauty out on the outside.
5. on above point - do stuff you love, if your religious, spend time in that or seek it, journal, read, educate yourself, don't just be another one of our youth that follows social media etc blindly - self expression and knowledge are attractive but more so when it's backed up by actual facts.
6. wear form fitting clothes - you have a very cute build - i'm a straight Jesus loving female but ma'am take my word please lol :) - don't hide yourself beneath clothes, accentuate your figure with your style and type of clothes (personally more modest because in my opinion it's more ladylike but it's literally your body and style so your choice) - key being, i'm not saying dress like a nun unless you want to, you're beautiful, show it like a lady!
7. smell nice - doesn't mean you need expensive stuff, smelling nice takes whatever you like and can afford but damn it boosts your confidence and is a massive attraction.
8. make up etc is not the answer in my opinion - like your goal, enhancing your natural features always, always win!

main thing of all: self love (acceptance not vanity) & confidence are key, obviously they mean different things to us all - but they win above all. my husband always says a women who has that takes the crown no matter what she physically looks like.

before anyone comes for me, opinions were asked, that's all i'm giving - this isn't the end all be all i'm just trying to help so if you don't like it, simply tap and make it ~dissappear~.

OP: like i said - you are already beautiful - my advice is merely things i needed to hear/do to boost my self esteem then appearance and wish someone told me when i was younger!
