run a bit to trick earrings

[AlexanderIII]

Dear all,
this from the sketch 'Professional Youth' (1923) by Dorothy Parker.

GIRLS WILL BE GIRLS
The funny thing is that if you took only a quick glance at them you would think they were nothing more than regular girls. They may run a bit to trick earrings, and it is evident that much of this talk about rouge and lip sticks has its foundation in fact.

I guess run a bit to trick earrings is about the same as to (take) trouble to be obliging, thoughtful and so on to coax (from, say, father or husband) earings. Is this correct?

 

[Barque]

The expression "run a bit to [something]" means to have a tendency towards something, or to have a habit of doing something.

These girls appear to favour or regularly wear trick earrings ("trick" is used as an adjective to describe "earrings" but I don't know what exactly they are).

Beat me to it.

I see. Thank you, Barque and Dermott.
