Luminous cushion for oily skin

I have oily skin. To give you an idea... my pores are on the larger side, and my T-zone tends to get particularly shiny in the summer. In the winter, my skin doesn't feel tight or dry, but even then, oil still comes out in the T-zone. Perhaps that is why I tend to use powder often, but I would also like to try a cushion foundation that gives a dewy finish. What dewy cushion foundations are suitable for oily skin?
