If the Lady is flying in F, she's several steps higher than MichelleFR, who usually flies FedEx. She therefore deserves sensible answers, and not your sexual innuendo.

If she chooses to dress like a Lady when flying F, that's a GOOD thing.
If she's comfortable with what she's wearing, that's nice.
If she looks better that the usual tracksuit/PJs crowd, good for her!
If her OH looks like her PA, she can console him later.
