New job - need to raise my wardrobe game

[Helicoptopus]

Can you please help? I just finished week 2 of a new job. It's in a very impressive office building and for that reason, I think, everyone is a lot smarter and more stylish than my last role which was in the same sector but in a more dowdy building. Interesting to see how everyone walks that bit taller in lovely surroundings!

Anyway I usually stick to soft black trousers, a dark one colour top and patent heels. Acceptably smart but no real personality. I am busty (18 on top, 14 bottom) with a saggy tum. I cycle so have toned but quite hefty calves. My arms are toned.

Any thoughts on stylish office wear with a bit of personality? I have never worn dresses but wonder whether now is the time to start. Your thoughts would be gratefully received - thanks
