Can you help me find a beret?

[GinGeum]

I’m looking for a wool beret, preferably pale blue or light grey, but it must be 30cm in diameter which is the tricky part - all the ones I’ve seen are about 25/26cm.

Any ideas of shops I could look in if not online?

Try an army surplus store for an Army Air Corps beret (blue) or a QARANC or Scots Greys one (grey). Plenty of sizes & you can shape it to your style in cold water.

Accessorize?

Try Accessorize - theirs were fairly wide this year (I have a v small head and was disappointed!). They have a few different styles and colours too.
