UPDATE: NOTE THAT SINCE I PUBLISHED THIS POST I HAVE POSTED A VIDEO TUTORIAL HERE ON A SIMILAR STYLE DRESS.
The first thing to do is to make a maxi skirt using the tutorial I gave here. Create the split by only sewing the top 30cm (or so) of the long seam together. To make the bodice you will need around 2m of fabric - preferably silk, with a width of between 50cm and 1m. In this tutorial I have a crop top on (admittedly not very sexy at all) but when you make yours you won't be wearing a top of any sort underneath.
1. Place the strip of fabric over your shoulder.
2. Tuck one end of the fabric into the maxi skirt.
3.Twist and tighten the fabric over your shoulder, making sure to cover your breast properly.
4. Still twisting, bring the fabric around behind your back.
5. Bring the fabric across the front covering your other breast.
6. Bring the fabric around tightly behind your back again.
7. Keep wrapping tightly until you have run out of fabric. When this happens tuck the end into the wrapped fabric and stitch down.
This is the dress without the crop top on - I have done it a bit tidier here too.
I've made another one for the wedding I am going to but I still can't decide which to wear. I'll be adding a few little extra details on the day which I can't wait to show you. Do you know what the best thing is about this dress? Once you've finished wearing it you can unwrap the fabric and use it for something else. You can even unpick the maxi skirt and use that too! That's what I'll be doing once I have worn these dresses... Talk about recession chic.
