Lace Up Dress

I have a wedding dress lace up back and I do not know about the life of me how far the summit is supposed to be outside what is supposed to look like the V and how it should be close. If anyone knows what I mean can you please help me, perhaps with a website or step by step instructions. HAHA thank you soo much

I think you're just supposed to lace it until it fits snugly (very) close to your chest. Then you just attach to the bottom. In passing, it seems better if you understand where the lace will be top and work your way down not up. The arch in the lower back is much more interesting lol. :)
