We have seen Blossom’s “second best manhunting summer ware” before most notably here. She wears it enough that it’s reached a level of notoriety with her coworkers. Generally, it suggests she’s desperate, though when she is, she’ll leave nothing to chance.
Certain drummers should watch their backs.
On a side note, Erika and Blossom’s working relationship has evolved into gentle, snark to snark combat.
