I was asked to make a flower girl dress a while back in ivory and sage green. I was given two weeks to make it, brief instructions as to what it was to look like, as well as a bag of satin and lace. The dress needed to look like a mini version of the bridesmaids dresses, but there wasn't a pattern available for a tween girl that was exactly what they were after so I ended up using the Burda 9697 dress pattern and altering it.
The skirt was cut on the bias and it had to be left for a week to hang and allow the satin fabric to drop. Unfortunately due to the quality of the fabric given to me it ended up dropping 3 times after I had hemmed it! Several times I had to arrange fittings with a very patient young girl and her mother and re-sew where it needed it. Next time I will have to make sure that I get more than two weeks notice so I am not madly running around with scissors and a tape measure. LOL
The lace overlay was hand stitched in place around the waist as was the satin bow. I stitched a pendant on the bow that could be removed when the wedding was over so the young girl could have it as a keepsake after the big day when the dress would no longer fit.
