I find it wholly necessary to carry two or four pairs of shades in my inappropriately large bag (to suit my mood at any time. I also find a pair useful for shielding my eyes from taxi drivers ― the only men who approach me ― as they attempt to catch my eye in their rear view mirrors while proposing marriage. My life is sad. I know.)
Big harlot kisses.
P.S. When I say "must-have," I obviously mean for myself (and not you. LOL) We can't go around wearing the same pieces, now can we?!
