Peacocking should be thought of an "enhancement" not a "crutch." I totally wouldn't discount peacocking because it will help if done right. Yet I wouldn't lean on it as something that you need to close a pickup or attract attention.

Peacocking can either make you seem irresistible if it's congruent with your personality/frame or it can expose your insecurities if it is incongruent with your personality/frame.

My best advice is to find something personal that works for you...

Here are a few things that have worked for my personality/frame:
1. A nice watch. I collect watches... not just any type of watches... Watches that stand out as being completely out of the norm. My favorite watch is a Diesel watch with a white enamel band that I get 3-4 compliments on per day when I wear it out. It was only $300 but it gets more attention than my $1200 TAG. HTX is also a nice, affordable brand that gets a lot of compliments.

2. A well-put-together outfit. Forget about feather boa's or leather pants if you're not a rock-star or don't have a rock-star personality/energy. You should choose something that matches and is something that a well-dressed guy would wear. When in doubt it's better to be over-dressed than under-dressed. Have a nicely fitting (get measured by a taylor) button-down shirt that isn't too tight or too loose. Go to a nice department store like Nordstrom or Dillards and have one of the sales associates help you pick a shirt that fits well... Here are the minimal essential outfits that nearly every PUA guy should have:
-Outfit #1& 2:
-1 Nice Fitting Button Down Solid Black Dress-Shirt to be worn tucked in
-1 Nice Fitting Button Down Solid White Dress-Shirt to be worn tucked in
-1 Nice Fitting Black Dress Slacks that go with the two above shirts.
-1 Nice pair of black dress shoes, black dress socks, and black belt to be worn with the above outfit.
-Outfit #3:
-1 Nice Fitting Button Down Printed-Design Dress-Shirt to be worn untucked
-1 Nice Fitting Pair of Jeans to be worn with the above untucked shirt.
-1 Nice pair of white business-casual shoes (like K-Swiss), white business casual socks, and a nice white belt to be worn with outfit #3.

3. Quality Cologne: Let me make myself clear. NO! I am not saying that you should douse yourself in cologne. I'm just saying you should smell better than Axe body-spray Phoenix... Here a list of the 5 most popular colognes in 2012. You should test them to find out one or two that work right with your body-chemistry.
-Polo Black
-Armani (Original)
-Aqua Di Gio
-Dolce & Gabanna
-Armani Code

4. Ink... Let me make this VERY clear again... NO! I'm not saying you should go get tatted up! But carrying a Sharpie in your pocket can open up some AMAZING doors if you're creative enough. Last week I found myself at a costume party that I didn't plan on being at. I used the sharpie in my pocket to draw a huge handle-bar mustache on my pointer finger. Because I was the only guy there not in costume, I attracted attention. Guess what the shit-test question was? "What is your costume supposed to be?" I just held my finger up to my upper lip and and said I was Magnum P.I. For most guys it is try-hard unless you have good inner game...

Here is another fun game you can do with a sharpie. I'd make sure you have great inner-game to pull this one off before you try it... Take Style's "cologne opinion opener" to the next level of creativity. "Hey... I need a female opinion... I'm trying to find out what cologne works best for me..." Wear 4 different colognes... one on each wrist, and one on each side of your neck. Ask the girl to sniff the ones on your wrists first and tell you which one of the two she likes. Then get her to mark a tally mark with the sharpie on the wrist that she likes better. Then repeat the gambit with the colognes on your neck. After 7-10 approaches like this you should have a nice amount of "tally-marks" on your neck that will get attention from people. They will ask "what does that tally-mark tattoo on your neck mean?" This will be an opening to tell your cologne opinion opener or completely ignore the question and start a new topic. I'd suggest you eventually get to answering their question though... because guess what... those "tally-marks" on your neck aren't just peacocking... they are a form of social-proof!

Hope this post helps to be constructive instead of some of the destructive ones posted earlier. Best of luck man!

p.s. Don't freak out about the sharpie, it will come off with just a little rubbing alcohol...
