2 ideas - Box Pleats or Knife Pleats (formal dress progress)

As the title says 'Box pleats or Knife pleats'? I have had to take out the gathers from the dress because the Dutch Satin is very thick and the gathers are looking very uneven. So I went to my textiles teacher and asked her opinion and I know that gathers are very 50s, I wasn't sure what to replace it with, so she gave me the suggestion of box or knife pleats, or a box pleat in the middle at the front and middle at the back, while the rest around the waist is done with knife pleats. I don't know what to choose because I want to maintain the 1950s look. How close/far should I make the pleats to each other? Box pleats or Knife pleats? So many questions in my mind.

Box Pleats

Knife Pleats

What do you think???

This is what my dress currently looks like:

Progress on my formal dress

Well here's the thing, I was meant to start making my official formal dress last weekend but got stuck when I didn't know what to use to transfer my pattern markings to my fabric. But lucky for me, my friend helped me with that and gave me the solution. So here it is, I had transfered all my pattern pieces onto interfacing and because I had done so, all I needed to do was go over the markings (pressing hard) with tailors chalk and the markings should go through. And it was as simple as that :)

Update!

I did some more work tonight and here is the progress:

Buy One Get One FREE! Spotlight Special

Yesterday I took a trip to Spotlight (said so simply, I actually begged the heck out of my mum until she took me) and bought a few things which I needed for the making of my formal dress and found some excellent patterns; McCall's 6547 (for my sister) and New Look 6723 (my pattern) and material for $1, which I'm unsure what exactly it is.
