Narrated Abu Huraira: A man stood up and asked the Prophet about praying in a single garment. The Prophet said, Has every one of you two garments? A man put a similar question to `Umar on which he replied, When Allah makes you wealthier then you should clothe yourself properly during prayers. Otherwise one can pray with an Izar and a Rida' (a sheet covering the upper part of the body.) Izar and a shirt, Izar and a Qaba', trousers and a Rida, trousers and a shirt or trousers and a Qaba', Tubban and a Qaba' or Tubban and a shirt. (The narrator added, I think that he also said a Tubban and a Rida. )
