I've actually gotten quite good at peacocking myself over the pass year or so.
It's actually quite hard to explain. Wear things that will get reaction. I know it may be hard to differentiate at first what is too over the top and what is just different.
It comes with experience. Once you start getting compliments, you will know what works and your sense of style will grow.
For example, early this summer I picked out this blazer jacket at H&M

It's different isn't it. It's flashy, it's not like all the boring blazer other guys would wear. I lost count of how many compliments I have gotten, from guys and girls.
If you're attending a formal social event and you wear this over every other guy's normal one-color blazer. You will stand out and women like that because it shows confidence.
