White shirts for men

Deciding what to wear everyday is a real pain. I've decided to stick to white half hand shirts. Any advice on where I can buy white shirts at a reasonable price ? It would be nice if they don't get crushed easily or don't have to be ironed. Secondary request: For pants, I would really like some low cost alternative. Just going to get dark colours. Right now the best fit I can find is the stretchy pants at Indian terrain which are real comfy.
