Interview wear for size 18

[NoFucksImAQueen]

I'm hoping to have an interview soon. Iv put on a lot of weight recently and I'm wondering what I should wear. I'm a size 18, hourglass figure when I'm not fat and fairly big busted.
Any ideas and tips much appreciated
Interview is for children's support worker

I would go for smart tailored trousers and a blouse/shirt

Thanks squig

I wore this to 2 interviews recently with a navy jacket and heels. I'm a size 16 with a big bust/hips also a big stomach. I found it a very nice fit (and I got offered both jobs!!).

Ooh that's a good sign Pinot. I think I would feel more comfortable in a dress as I find trousers very restricting. Iv gained weight very quickly so I'm not very good at buying for my shape.
Iv looked around and found this.
Do you think it all goes? I might order this and a dress and see which I prefer. Money's a bit tight but I can always send back the one that I don't wear

That outfit looks great. I love the shoes!

Thank you. I wasn't sure if they'd be too casual but I'm not great with heels and they reviews say they are super comfortable
