I am not sure about the meaning of the verb ground in this sentence from an online article.
Accessories were kept polished and stylish with taupe suede Manolo Blahniks grounding the look and simple diamond stud Adina Reyter earrings for subtle sparkle.
Does ground mean connect with the ground, place on the ground, or give theoretical basis to? None of the dictionary definitions seem to work here. What does the sentence mean? Manolo Blahniks supposedly refers to a pair of shoes designed by Manolo Blahniks, but how do shoes ground a look?
