Nice thought, but out of touch with reality.
Most women have more than one dress…………
Today’s women don’t do their own sewing and add cloth to lengthen dresses or raise necklines.
I can’t imagine Mrs. CTL or our daughters trading their decision making power for a little diamond ($5,000 doesn’t buy much of a quality stone these days). This is not to say the CTL women wear short lengths or low necklines).
Better to say, ‘darling that dress doesn’t flatter y, why don’t I take you shopping and treat you to a new dress that makes you look spectactular.
