Packing cubes, trainers & a light jacket

[Peopleplease]

Have a few queries so sticking them all in one thread.

First: I’m looking for a small set of packing cubes for packing a large suitcase for me & 2 kids. We do shortish trips so I want to keep stuff seperate but a lot of sets just have bigger cubes whereas I’m looking for smaller cubes. Any ideas?

Second: I just bought these but they’re a bit tight. I’m not certain about the toe shape. What do we think? www.nike.com/ie/t/cortez-basic-sl-older-shoe-VhXt0V/AH7528-100

Third: after weight loss I don’t have a lightweight ‘spring jacket’. Are blazers still in fashion? What else should I be looking at?? I was thinking a kakhi jacket of some description?

Packing cubes from Amazon: we have a set each, in different colours, one small (underwear), a medium and a large, plus a set of small green ones that hold chargers, cables, adaptors etc.

Blazers are again the thing, and there are a gazillion out there, at every price point.
