OLIXIS 64"x21.5" Arched Full Length Mirror with Stand, Body Mirror

From the brand

Can I actually hang this on the wall, or is it just for leaning?

You can do both! It comes with a stand for freestanding/leaning use, but it's also designed to be mounted vertically on the wall if you prefer a more permanent setup.
Does it distort your reflection? I've had cheap mirrors that make me look stretched or wavy.

No distortion at all. The 3mm high-definition glass with upgraded silver layer gives a perfectly clear, true-to-life reflection without any stretching or warping.
Is this mirror stable when leaning against the wall? Will it tip over easily?

Yes, it's quite stable when leaning. The included stand allows you to adjust the angle so it sits securely against the wall. We also recommend using the included anti-tip hardware if you have kids or pets, especially if you choose to mount it.
Is the frame actually metal or just plastic painted to look like metal?

It's real aluminum alloy—lightweight but sturdy, with a sleek matte finish. No plastic here, so it won't warp or fade over time.
