Teeth. If they aren’t straight or there are other dental problems fix that first. It’s good for your health and makes a huge difference in other’s perception of you. Next comes general fitness. If you are overweight, work on that. Finally hairstyle and clothing. You don’t have to spend a lot to look good. Get an objective opinion from someone you trust to tell you the truth.

Having grown up with women obsessed with beauty and grooming. I've learned a lot. I'm considered more plain than most family members. As I haven't had surgery and I'm boring for being natural. However they have taught me a lot! As the beauty queens lol have specific routines... so here is my essential daily routine.
1. Healthy diet. Feed yourself good nutrition and you will feel better about your body.
2. Mind, body & soul - take care of your mind as you do with your body, it is pointless having a great body but the mind is a wreck. Your health will eventually depreciate. The mind , body and soul are connected.
3. Exercise releases endorphins and give you an amazing body. Love the body you're in.
4. Find the correct shades of make up, hair style/colour, clothing that flatters you for your body type.
5. Grooming; eyebrows, hair, hygiene, a scent that compliments your natural body scent, lazer if you don't like shaving or waxing, micro-blading, facials, massages, mani's & pedi's, permanent make up (don't do anything if you're not ready as you might not like the end result, so get the best to do it), chemical peels for problem skin.
6. Teeth - take good care of your teeth, braces, veneers, clean & polish.
7. Hair have a good hair care routine
8. Good habits help long term so enough sleep, removing make up before bed (wearing make up with less harsh ingredients that tend to ruin skin), lots of pure water, stop smoking, stress less.

Do what you want, do what's going to make you happy because any person that tells you not will still look at the girl who takes good care of herself. That goes especially for guys, they have a lot to say about these women but they will still choose these women over plain janes.

Other: Exercise to have a toned body, taking vitamins and avoid coloring products to have shiny healthy hair, getting braces if teeth are crooked, take care of your skin to keep it healthy and youthful

Those are fairly superficial.

for me, how a girl dresses, her attitude, confidence, are far more = attractiveness

go for change in style, make over etc before anything draconian.

Absolutely one and two.

None of the above. Gym membership.
