Nothing Elegant

I thought I might be able to grasp this one, it starts with an idea of a single charm being doubtful, but the rest of the poem is populated with if statements and then “something” becomes upright and I’m not sure how we got here.

Perhaps she means having doubts is charming? And perhaps if we have doubts about the poem but we still enter it then just asking “if” is enough to make us upright morally speaking? Perhaps being earnest is the highest praise she can offer us for at least attempting to dig into the heart of her rose? And maybe that’s why the poem is titled “Nothing Elegant” because she doesn’t want us putting on airs?
