Answer:
Cotton Shirts
Step-by-step explanation:

Cotton has tiny pores that enable the sweat to evaporate off your skin, and hence keep you cooler. At the same time it absorbs this sweat, allowing easy evaporation. Synthetic fibers hold heat in, and do not allow sweat to evaporate.
It would be that Rana should buy cottons shirts for summer.
