Hi there
I actually tried on the dress in the shop where I eventually bought my dress !!!
Lke Gillsy commented, go to the Alfred Angelo website and find the stockists. You want to be looking for ones that stock the gold range (i think) or premier (can't remember which) and they should stock one of the full range. My dress is an AA dress and I loved them and the prices were a bonus too
I was torn between 1136 and 2019, and I went for 2019 as it gives you the tiniest waist
I wasn't sure about it on the hanger, but the woman in the shop suggested it and I felt amazing in it that I bought it the next week and it was only my third dress shop.
Hope you find the dress
