Ikea Frakta bags are very useful when transporting clothing. You can fit around 35 shirts or skirts. Only 20-25 larger dresses will fit in a bag. You can zip these up while the clothes are still hanging on the rack and leave the hangers hanging out of the top.
These are much cheaper at Ikea, but can only be purchased online. Ikea did announce they plan on using a 3rd party to start shipping goods, so they might be available online direct from Ikea at a better price in early 2018. In the mean time, even at normal Amazon prices, these are a good deal for the amount of work they save you.
