The colours show much better on the before picture though. Basically I underestimated the thickness of the fabric and went for a drawstring at the waist. The peplum-thingy was also a questionable decision. The only thing I regret is the lack of pockets in the new version, I could stuff things inside when the waist was held together. I might add a pocket at some point and maybe a collar. \
Not sure about the resulting peplum either. I sort of feel like with a cleaner drawstring design it may be okay as-is, but better with a hem like you’ve done along the neck and chest to accent and give the peplum a complete, consistent look.
Also if you mean directly beneath/behind the drawstring, rather than below it, then yeah maybe something like you mention to give it some more definition wouldn’t hurt.
Not sure if my first message was clear, there’s two problems going on here:
Comfort wise, the general belt area is too thick, so I would change the construction.
Look wise, I don’t think the bottom would look good (on me(?)) if it were to stop with a drawstring and I’m still brainstorming ideas for that. It was all finished with a really cute red bias tape with little daisies though, I wouldn’t change that.
