My friend. You may have opened a can of worms here.
To put it simply, I highly advise against you purchasing a bench shirt if your goals are as listed below.
You will need to Powerlift to benefit from the shirt and why buy the shirt if you do not plan on competing.
To reap the benefits of the shirt you will need to develop lock out strength and tricep strength. That can be achieved by doing a "Powerlifting" style routine. You cannot jsut throw a shirt on and be the man. The shirt will put you in a groove that you are very unfamiliar with and you may have flaws in your form, a Powerlifting bench form is quite different.
There is certain equipment I would recommend for people even if they never plan to compete or even Powerlift at all.
Groove Briefs can give excellent hip support for people with problematic hips or wide stance squats.
Wraps (wrist or knee) can have their place in any routine.
A good Powerlifters belt can also help when going heavy.
You DO NOT buy a bench shirt to increase your raw bench, that is a case of your goals and principles getting a bit jumbled up.
Save the cash and go take some girlie out, you'll probably get more out of teh girlie than the bench shirt .
