Stylish, lightweight spring jacket that goes nicely over dresses??

[Nighthogs]

Currently sweating in my Barbour coat and realise I need a light jacket that looks good over smart/casual dresses and tights/leggings (I'm a teacher).

Please hit me with your recommendations!

Anyone? 🙏

A utility jacket on the smarter end of the style? Something like this one:

Or this if you're looking for something without a belt:
