Praying Salah with Half sleeves and rolled up trousers?

If the half sleeves are because the design of the clothes(t-shirt as example) is like that, it is okay. Don't rolled up your long sleeves T-Shirt, as a sign of respect to our God. I do agree with the lower garment part, it is better to rolled it up. But its not that your salah will not get accepted. It is not among prohibited act or conditions.
