Show me your wedding dress before and after alteration photos.

I started wedding dress shopping today and I’m finding dresses that I love except [insert single detail about the dress that I don’t like here]. I’m wondering what woes can be cured with some good ol’ fashioned alteration.

How have you changed your wedding dress to make it perfect for you? What’s possible? what alterations cost the most/least?

I’m particularly interested in neckline alterations, whether it’s adding decoration or changing the shape. Of the bust/neckline entirely. Also...given the season (we are going to have a fall wedding), possibly adding sleeves?
