Back to work wardrobe (reward/ inspiration for losing weight)

[Schoolandstuff]

Am back to work in early September after mat leave. Have lost one stone but hoping to lose another to take me to a small size 12. 5"9, hourglass, but large bust. Corporate environment. Think will have £2k to spend on new work wardrobe. Can anyone help with a little capsule suggestion that will help me feel more confident going back? Prefer skirts/dresses to trousers. No need for suit but yy to nice jackets.

Is that enough to go on Thanks!
