Workwear inspiration needed

[GherkinSnatch]

I'm organising my return to work (retraining as a teacher) and I'm looking for outfit inspiration.

I know the sort of thing I like the idea of (slim leg/ankle grazers, slim belt, tucked in but not too close fitting shirt) but I have the fear of getting it wrong. I'm a size 12/5' 9"/large of breast if that helps at all (so I wouldn't be looking for turtle necks).

Thanks!

If you can, it worth checking what others are wearing. I have changed schools this year and now have to follow a stricter dress code: trouser or skirt suit or dress and blazer. My quirky separates and colourful cardigans are languishing in the wardrobe!
