Venus helps with that. It can gradually change your appearance, but only to highlight your good sides and hide your bad flaws. It should also improve your dressing style, if you're open-minded about it (if you are a guy, most guys aren't very open-minded about that, which results in them adopting the bad habits of their peers and thus dressing in a forgettable, bland way.) Green is the colour to use.
The Sun is important too in this, as it improves one's confidence and optimism, which changes how we view ourselves, thus helping out beauty surgace. It also improves our health and give us a healthy outlook, which are important in bettering our appearance.
From the physical side, what makes the difference is:
• how you carry yourself;
• how you dress;
• if you're a male (which your username seems to corroborate), to be lean and harmoniously muscular (not bodybuilders who look like monsters and inflexible and neither weight-lifters who are tend to be a little on the excessive side, depending on their innate constitution
• if you are a female, to be lean. You can wear make-up or not, but do not wear one ton of it like actresses.
So the physical components necessary to maintain beauty are: hygiene, fitness (in relation to your constitution, as we're not all the same), style, posture and stride.
