For Simplicity 8458 I used a size 20 but I took off 1.5 inch, so next time I will size down in the waist and grade to the 20 for a puffy skirt. The skirt itself was quite simple to make although there are somethings I would do differently. For instance I sewed the lining and skirt as one piece, on the next go round I would attach them at the waistband and sew them separately. I think that would make hemming a bit easier. Speaking of Hemming. I waited until I got my Petticoat to complete (which was an excellent idea) because I took off over 5 inches. I did like the original length of the skirt and am searching for a longer petticoat.
The fabric was a party print from Joann Fabrics and it took me forever to find a matching pink for the top.
For Simplicity 8386 I added flowers to the bodice. The shirt itself seemed to regular without some additional items.
