Floral dress revamp ideas

I got a little catalogue through from next, just a little spring one that they just post out for free so I thought I would flick through it.  I didn't have the intention of buying anything but it is useful to look at ideas sometimes for putting things together or items you might want to make.  I have had this floral dress in my fabric bag for a while that was given to me for the fabric.  It is a nice dress it's just a little dated so i have been wondering what to do with it.

The length is a bit long and the sleeves a bit flouncy so they will definitely have to be changed but the next book also gave me this idea...

This little skirt is £38 on the website! I would not pay that for that little bit of fabric but its a possibility out of the above dress only two layers I think though as there is not enough for three and maybe three is a bit much?  So that was one thought, another thought is leave it as a dress but change the style..

Little thin straps?  (£28  this dress)

Or halter neck ?  (£25 this dress)

I'm not sure which I will try but that is my project for this evening and it is a much better option I think than paying those prices (but then I wouldn't) I will show the results tomorrow.  I also don't understand why the dresses are less expensive than the skirts, surely there is more fabric in a dress and you have the full outfit.
