The clothes posted are awesome, but the opinion that you need to dress up like this to attract "top level talent" is plain wrong. You should dress nice when an occasion calls for it, or wear those fly new Jordans when it's a look you like on you, but dressing up like the Playa Haters Ball when you're going out to the club reeks of insecurity.
Talk about projecting.
Truth is I agree with you to a certain extent. I am not an advocate of suiting up when hitting the clubs, because people there only suit up if they have attended a special occassion before like: wedding, fancy dinner, etc. When I go to the clubs, I always run into people I know so it's not practical for me to suit up. However, I'm not saying it reeks of insecurity, and if I saw a guy pull it off with authority, that would be the last thing on my mind given the social pressure to fit in and not overdress. It takes balls to do this, and people do notice when done with complete authority, meaning you own the fact that is how you chose to dress.
However, the simple act of wearing plain clothes, lets say a white oxford and dark jeans with a navy blazer, all of them with a very nice slim figure-hugging fit, is more than enough for me to get jocked heavily. Dressing "nice" for me means going a step beyond what the situation calls for, but not overdoing it. This is more casual-dressy (dress shirt, pants/jeans, blazer/jacket) than formal style (suit).
I think it's a great exercise to try out, even if it's just to expand your comfort zone. Go out and put on some stylish clothes, and just observe what happens. Most of my friends who choose to underdress and fit in, do so mostly because they feel insecure about being the odd one out, and not so much out of comfort. Funny thing is, since me and this close buddy of mine upped the ante when dressing up, now they are dressing up themselves and feel more confident.
This is shit that is totally in your control to handle, why not make the most of it.
