Blazers: A blazer is a great piece that can help you achieve that smart work look but can also look equally fabulous with jeans - okay, not for the playground, but certainly for a smarter casual look. Or consider a cardi - there are some fabulous styles and colours.
Dress trousers and/or a skirt: These will help to complete your work set.
Jeans: Buying a tidy (no tears, dyed patches etc), dark pair of jeans can double as your "casual Friday" look (if you have that at your workplace and if you work on a Friday), especially great teamed up with your blazer.
And then, as we all know, jeans are fabulous for kicking around in casually. Look for jeans with a stretch - they're more comfortable and forgiving.
Shoes: A great pair of leather ankle boots with a slight heel can be worn with your work trousers, skirts and dresses but are also great for a casual look with jeans. If you get them a little dirty at the playground, give them a clean, polish and/or brush and they'll be as good as new. Flats are a great shoe style that can be worn in both situations.
If budget allows, it would be great to have a plain-style court shoe with heel that you can wear to work with your trousers, skirts and dresses, and in the evening.
