Dresses are very similar to shirts in the way they are ironed, you effectively start at the top and work your way down in a logical sequence.
But they're often more fitted to the body, making you use the ironing board to iron smaller sections at a time, in other words - only what you can get flat.
Dress Order
3. Dresses often have loose flaps on their reverse edge and it's a good idea to iron these so they're flat before doing the body.
4. Yolks are the obvious next choice as doing these later would mean potentially creasing another part of the dress.
2. Collars are next (you can look at shirt ironing for tips on correct procedure for different types of collars)
5. Sleeves on women's clothes are often meant to be finished round (i.e. without a crease)
1. Any removable feature such as a belt should be ironed first then put on the hanger so you don't forget them.
6. Bodies are done last because you want to move the garment the minimum once the body is done.
