Anyone bustier bought from Unfolded and found the sizing accurate?

[Topbird29]

Unfolded - has anyone bought from them that is bigger of chest? What is their sizing like? I am thinking of getting a dress, and maybe a shirt. I'm quite busty though, and 5 foot 6 - would usually be a 18 or 20. Just want to see if size 20 would be suitable.

I would go up a size - the dress I ordered from them was lovely and great everywhere but the bust was tight.

@FlapperFlamingo - thanks. I've gone got a 20 so fingers crossed - although it should take a little while to actually come!
