Best interview outfit style for heavy chest?

[Doorstepcountry]

Looking for any fashion/styling tips for looking smart for an interview while dressing with a out of proportion and heavy chest.

Bought a beautiful blazer from Zara, buttoned it up and my chest looked ridiculous, making me look much heavier than I am and it was inappropriate even with a high neck loose top. Unbuttoned it looked ill fitting no matter the size (ordered 3 different sizes).

Do I need to buy slightly bigger dresses to disguise my chest?

Massive boobs here and a corporate job. Things that work for me:

Firstly blazers and jackets you can just wear open, they looks better like that anyway, so they don't have to do up.

I have a lot of dresses from whistles, which I find flattering without calling lots of attention to my bust. I recently bought one called Olivia and one called Lola.

T shirt tucked into a work skirt or trousers, with a blazer or jacker on top. Or a smart cardigan. H&M often has good work tops that looks much more expensive than they are, in nice fabrics.

Nothing low cut and no polo necks.

There is a brand called Closet sold on Asos which is has some good options.

One more thing, it's mostly about the shape of the clothes... If they are cut in a loose/boxy way then a different size won't help. You need something tailored with a waist.
