The speaker is caught between wanting affection and fearing what it costs. Someone has called them pretty in a green sweater, and that small compliment stirs up something painful as well as sweet. The repeated "57 percent polyester" is a cold, factual detail set against strong feeling, as if the speaker is clinging to something ordinary to stay steady.
What they want is simple: a kiss that is just a kiss, a hand that stays in theirs, and love without a power struggle. The imagery of claws, biting, hunger and "hit and run" shows how they expect closeness to feel, like a contest where someone gets hurt. They also describe their own love as heavy and clinging, something that sticks and doesn't wash off, which suggests they worry they are too much.
The mood is tender but anxious, and quietly sad. The last line is a plea, almost childlike, to be seen and valued without having to give up their body or their safety.
