This is what my boys are wearing to CRT for breakfast on thursday (!!!!!) I made the outfits for the Twins Days Festival parade in Twinsburg OH this summer, and they get to wear them again to meet the princesses they are so smitten with. The glass slippers totally made the outfits and were $5 for 6 at
Amazon.

I adapted the Carla C Scientific seamstress bowling shirt for this, just made the placket and the shirt all one piece (taped the pattern pieces together to cut it, then folded it over, did a banded collar instead of the standard bowling shirt collar. They were definitely a labor of love, each one took probably close to 5 hours between the trim and the embroidery and all that. They are off-white stretch twill, though, and the epaulets on the shoulders I attached with snaps so they remove for washing. I have even washed them and they laundered great!
As a backup I made these t-shirts since OH in August is H-O-T.

And the back
You could adapt really any of the princes outfits, maybe prince Eric's black-pants-white-top thing or Prince phillips tunic over a shortal he could wear for the meal then the take off the rest of the day.
We leave TOMORROW! We're driving to Milwaukee to fly out at 6 a.m. on wednesday. it's about 2 hours and there was just no way I could get us all out the door at 2 or 3 am to get there in time. Yuck. But since flying out of milwaukee was $500 cheaper than o'hare, even paying for a airport hotel room for one night we still came out WAY ahead.
I did not get all my projects done,

and threw in the towel on the buzz and woody bowling shirts I have had in progress for months. They have SO many appliqués and I messed up one so I have to redo it, and I had to add the plackets first before I embroidered because of the placement then I couldn't figure out the best way to line them, and the fabric is too thin not to line them, so I said enough! Thankfully the ONE set of bowling shirts I had from last year that still fit are the Buzz lightyear ones so they are re-wearing them.With my kids' crazy preschool schedules, parent/teacher conferences, their total lack of napping and my husband working 9 days straight so he could take fewer vacation days for our trip, it just wasn't getting done.
Got to get the rest of everything packed to go today and then we are Off! WOoHOO!
