How to spend 250€ on Zalando to prepare for summer?

Hello, I got a 250€ credit on Zalando.

Any suggestions on good stuff to buy?

I want to focus on clothes that will last decently but affordable price (I know it's very hard).

I definitely need to buy a light colored light jacket, but for the rest I'm open, pants/shirts/shoes etc.

I don't need a full wardrobe ofc, just a couple more items for summer (and possibly to not die of sweat in the office), mainly looking for suggestions for brands or, specific items/type of items.

Thanks u all.
