Not possible to reach or get, no matter how hard you try. It is used for goals, standards, dreams, and levels — things you aim at rather than things you hold.

There are two flavours of it. Sometimes it is a plain statement of fact: the target is set so high that no one could meet it. Sometimes it carries sadness or criticism — 'unattainable beauty standards' means standards nobody could ever meet, and the speaker thinks it is wrong to set them. That second use is very common now in writing about magazines, social media, and body image.
