Please help, how is left shirt image lightened? right one is

First of all, the light in the purple shot is coming from behind the collar.
Yours is from the front.

If you want harsher contrasts, try either moving the light back, or using a different/smaller modifier.

Ok. I position two lights on the image to the right. two softboxes, one in the top and one in the bottom with light coming slightly from above. but this i need to do other wise grey background wont show off as evenly lit.

i can try directing the light more harsly from the top and bottom if that is what better.. but not too confident about how the background will play out.

what kind of modifier do you recommend in order for me to achieve the wanted look? (left pic)

I got a couple of softboxes different sizes that i mainly use. maybe that is wrong? got one snoot . perhaps I ought to play with white/black cardboards among the light

Tad bit more care in arrangement would probably help quite a bit, particularly at the collar. Little bit of PP wouldn't hurt also.

In the left pic the background has a gradient, and to my eye only has one light source on the top. You might want to play around with the product setup. Place a translucent plastic box under the shirt, and an omnidirectional light source inside ("garyfonged" flash with an rf or optical trigger), then light the shirt with a directional light from the top. Or you could just use one large source close to the top of the shirt.

this will get you sharper shadow lines, but less contrast actually
