Ah, the question of when, where, and how to reveal one's underpinnings. A flash of a lacey bra, the hint of pretty camisole under a jacket, the deliberate reveal of a delicate slip--even as a senior woman , I adore it. BUT, there are always unwritten rules to be followed. What is pretty in the evening can look sloppy in the morning. What is feminine on a date can look tacky in the workplace. What works for one person can be a flop for another.
Your colleagues have given you mixed messages about your current styling--even if some of them were rather rude--so I I think you need to mull things over before continuing. If you are confident you can reset the unwritten fashion rules of your workplace without damaging your image or chances of promotion, then Ignore the naysayers. If you think your professional image might suffer by offering colleagues glimpses of your lingerie, then you might want to reserve the look for non-business wear where the glances will be admiring, not glowering.
