Blue skirt

The Blue skirt is a free-to-play Old School RuneScape item — “Leg covering favoured by women and wizards.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 123 gp and sells at 141 gp — a net margin of 16 gp (13.0% ROI) after the 2% Grand Exchange tax of 2 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 123 gp and a sell offer near 141 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
