Simplicity 2886: Sewing With Bedsheets

I was inspired by Sew Weekly's Make This Look Series. A cute dress from a shop is chosen and a pattern is picked out that might resemble the dress. I wanted to make an empire waisted sixties style like the cute polka dot dress above, but with an old bedsheet .

Here is my almost finished version of Simplicity 2886 . I still have to add a horsehair braid trim at the hemline to make the hem flare more stiffly. But first, I need your help. Should I leave the waistband plain  or add the white flowers? This dress is going to be worn by a teenager. I don't think this pattern looks much like the polka dot dress from Boden. I would have to lower the neckline and change the skirt to a flared a- line without pleats.

This dress was made from an old sheet I bought at the thrift shop. I soak old sheets in Oxi Clean to remove any old stains or odors. Yuck!

I cut some bias strips from green poplin ironed them in half, and ruffled them to create this pocket ruffle which was sewn down to the pocket before the pocket facing was added. 

I sewed a hand picked lapped matal zipper. I have a collection of old metal zippers and I love them. They give a vintage style project a really authentic feel.

This dress was underlined with white cotton. I will put the horsehair trim inside the hem allowance. In couture sewing, dresses are often underlined because it gives them nice body. You can sew your hems and facings down on the underlining fabric part only, so you don't have any thread marks on the outside of your garment.

So please help me, with the flowers or without?

Thanks!
