The Case Of the Unwearable Top

I recently bought this top on an American Apparel Groupon I had.
I think it's absolutely lovely, but I can't figure out how to wear it.
The lace is too open to wear without a tank underneath
and a tank underneath looks really dumb.
It only looks good tucked in to high waisted skirt/pants
But I don't have any high waisted jeans.
Help!
