Made my own Mod Cloth dress

I saw this dress on Mod Cloth months ago, way before it was warm enough to wear, and thought, "Wow, that's a unique design.  What a weird combination, actually.  But it's cute!  I could make that!"

So I bought some grey cotton for like $3/yard at JoAnn, used some ivory lace I already had, and added four (weird, in my opinion) two-hole buttons with the metal hole grommets.  The Mod Cloth ones are probably fabric-covered, but mine aren't.
I did not have the right pattern at all, so I had to modify one (Butterick B4915, now out of print).

I've had this problem twice before and both times ended up just sort of modifying this pattern, I think, when cutting.  Here's essentially what I did when I cut this out:

That piece would be the top, gathered into the bottom and neckline, and I also cut a smaller piece for the lining.  See them together:

I added some vertical tucks to my bodice as well as the gathers over the cups.  I assembled the dress as usual (this is one of THE simplest patterns in the world) and usd some of the ModCloth style elements, like the tiny pleats on the skirt instead of gathers, and... here it is!

 What's funny is, I thought this was a weird color combination, but shortly after I had cut this dress out I saw another, very similar one from Lulu's:

How megasimilar is that?  Although shorter and skimpier.
I guess grey and ivory is a color combination to watch this season!
