I spent probably about $350 all up on uniforms this year for two kids. That includes hats, sweatshirts and one pair of long pants for winter. And shoes but Ive had to replace one pair of runners for each kid.

Our sports polo shirts retail for about $30 and the formal uniform blouse retails for about $35. The sport shorts cost about $25. I bought the navy blue hats/sweatshirts/formal shorts from Big W because the school does not require the emblem on them.

ETA - We have four formal shirts, two sports polo's, two sports shorts and 6 pairs of formal shorts. 1x jumper each. A hat and a spare each. My boys wear sports uniform twice a week and formal uniform the other 3 days so I wash uniforms every second day
