What on earth is smart business dress?! I'm totally lost.

I have an interview on Thurs.

At the moment, I work at home, so no smart dress required. I don't have much money at the moment.

The only smart dress I have is this in orange which DP assured me is nice, and matches what people at work wear. But someone just pointed out that it's a bit low cut on another thread, and now I'm lost again.

I'm a 32E/F, so hiding my boobs isn't an option. I don't wear anything high necked, because it looks really top heavy and horrid. I tend to live in jeans and vests, but ripped my jeans last week and don't have any more. I don't own black trousers. At the moment, I'm wearing colorful playsuits that really aren't workwear.

I am utterly lost for what to wear. I had hoped to borrow something but DP's mum is a 14, and I'm an 8/10, and she only has a very posh wedding skirt. It keeps falling down, I can hardly walk. It looks stupid.

What on earth do I wear?

A bra intervention sounds like it'd be a good thing - I'm a 12-14 and 30G so as an 8-10 I can't see how you'd take a bigger back.
