I've seen Psychology Today being linked, and although this guy may get some flak for his looks and his "attraction doctor" title, he does have his PhD and several Masters degrees in the social psychology sciences.

Anyway, just a small tidbit he writes on looking BETTER.

A while ago someone posted from bodybuilding about women wanting to fuck a guy from tinder who had a picture of a male model up. Some of the replies ranged from angry("oh fucking sloots gon sloot argh") to sad("i can't believe women would do this to me...") but let's be real. If a model woman gave us a text on tinder we'd fuck her no questions asked.

Looks do matter and some of the more helpful posts were about doing what you can and raising your LMS by lifting, dressing better, more confidence, talking game, etc. It's true, you have what you have to work with, so get started and stop complaining.

quoted text from article

1) Grooming – by far, the most important feature. Take some time to care for yourself. Shower, style your hair, and shave or trim where you need to. Be clean, neat, and smell good too. Grooming alone can make (or break) your attractiveness - and all it takes is a bit of time, effort, and a toothbrush!

2) Clothing – also important and a relatively easy fix is your style. The research says that three aspects of clothing are required to be attractive – neat, well fitting, and more formal. Put plainly, your clothes need to be clean, pressed, and well maintained. They also need to fit you well and flatter your shape. Finally, they should be a little classy. Don't be chronically "under-dressed"...buy some dressier gear. Also, the color red is a good choice (see here).

3) Posture – practice standing up straight. Hold your head up. Put your shoulders back. Buy some sensible shoes, a good desk chair, or a corset if you need to. Good posture is sexy. It also contributes to the right body language for dating and relating (see here).

4) Attitude – remember to put on a happy face. Smile. Be pleasant, positive, and friendly. Heck, a good personality can even overshadow other physical issues you may have (see here). So, be happy...and get a date or keep a lover.

5) Fitness – granted, this isn't as easily "changeable" as the others (at least for me). But, the research is not talking about the "perfect butt" or "washboard abs" anyway. Essentially, we're shooting for "relatively healthy" (e.g. not super obese, no severely protruding stomach, etc.). So, no need to obsess and go overboard. But, do your best to eat well, move around a bit, and care for your health. Good grooming, the right clothes, and standing up straight can go a long way towards minimizing what diet and exercise don't too!

6) Gender – generally, try to look masculine or feminine (depending on who you want to attract). To be more masculine, muscle up your shoulders and chest (or wear a nice, padded, sport coat). Grow a goatee, chin-strap, or beard to hide a weak jaw. To be more feminine, learn to properly apply makeup – accentuating your eyes and lips. Also, grow your hair longer (or just get extensions).

This sub focuses on fitness and masculinity and to a big extent "attitude"(aka be confident and have game to talk), but we should also focus on grooming and clothing and the rest. You can't just talk the right way you have to look the right way. The study they did shows that putting effort into your entire life instantly makes you more attractive. Don't expect a complete turnaround and being surrounded by hot bitches by putting on a nice shirt, but everything counts and matters.

tl;dr - put work into your life for yourself and you will look more attractive, it's been said too many times here
