Wedding Dress

I have been lusting over a dress I found via Pinterest for months. But everytime I would click on the photo to go to the source it would take me to theknot.com.au and I still couldn't find the dress.

So I started trolling through websites trying to find something similar - I need to try something similar on to see if it suits me before I become anymore obsessed with this style.

Today someone on the Vogue forums posted a link to bridesmaide dresses. I clicked on it then decided it was ok to look at more dresses (since I hadn't looked at any today) and BAM there is my dress. The one I have been obsessed with for months. Here she is;

I love it! But I either need to have a boob reduction or get something similar made with a back. Oh and there is an an odd line around the thighs that I am just not a fan of.
The neckline & the small train is what is really grabbing me.

Ideally I want a detachable skirt so I can have a pencil skirt/dress for our casual reception. So that means I need to get it made and then my budget blows out big time. 

Anyways I still have 8 months & 20kgs to lose before I start dress shopping... I wonder if I will still be as in love with this dress then?
