[NSFW] Which females should you not give an open shelf bra and a thong or crotchless panties to for Christmas?

What female would be on your list of “never give an open shelf bra [NSFW], and a thong, G-string, or crotchless panties to for Christmas”? For instance, that woman you knew back in college that was like one of the guys and a strong confidant, your frequent but single female project partner at work or class, or your super cool, hip, not too old step-aunt? Is the list who you “would give to” immensely smaller than your “would never give to list”?
