Smart-ish tops for work - size 20

[Blueberryme]

My workplace is smartish (not formal) and with the weather starting to warm up I am looking for some new tops/blouses/shirts to go with trousers.

I find it very difficult to find tops in a size 20 that meet what I’m looking for so I wonder if anyone can help please?

Non-clingy - needs to skim over body but not cling when I sit down.

Not baggy and shapeless
No longer than the very top of thighs
Plain colours as I really don’t suit patterns - I like green, blue/navy, black, white, burgundy
High St prices - up to £30-ish per item

Vinted/charity shops - I already trawl these regularly

Anyone?

Maybe try Live Unlimited ( the slub T-shirts are good) or Seasalt?

I got some lovely tops that Vinted sold so not pricey, but they are Marina Rinaldi, and a German company that I found in Berlin called Ulla Popken. each top was around £10 and they are very worthwhile. Yours clothing can be useful and the catalogue companies Simply Be and JD Williams.
