Does this maternity dress exist?

[JimmyCorkhill]

I really want a denim maternity shirt dress. I have seen another pregnant woman wearing one but didn't think to ask her where it was from. I kind of want this sort of style but cannot find it anywhere on the internet (as a maternity one):
Fat Face dress
Acne dress
Can anyone help me please?!

I got one from h&m last year but not specifically maternity, I just bought 2 sizes up and it worked until about 8 months. Was brilliant after having baby too as was comfy but not 'lounge wear'.

new look not quite right but a bargain
next also not quite the same

Thank you! That's a good tip about getting a larger 'normal' dress. I actually have the Next denim dress in my bedroom at the moment. It looks fine in the picture but in real life it is made from a ton of fabric and makes me look even more massive than I already am
