Here were the girls' costumes. We just got everything out of their closets, with a few creative additions (such as the 10-year-old wearing an old 5T green blazer I knew I had down in our crawl space). My youngest wasn't about to wear the overalls and yellow striped tee-shirt Agnes usually wears, so we went with ballerina Agnes. Let's just say it was a loose interpretation.
I thought I'd post a quick how-to on making the minion costumes. They were so cheap, and relatively easy to do!
First we ordered yellow beanies off Amazon. I think they were about $4 each. We also bought the yellow tee-shirts from Michael's for $3 each. The glasses were an AWESOME find (also at Michael's) for only $1! We were looking for "nerd glasses" because we thought that would be close enough. Not sure what these glasses were supposed to be for, but they sure worked well for minions, and you can't beat $1!
For the shirts, we took some denim fabric we had, cut a rectangle and two strips to look like overalls, and then just stitched them down with a quick zig-zag stitch. We didn't even turn the edges under, because we figured these shirts wouldn't get used more than two times. We thought we were done with the shirts, but the kids kept asking about the "G" logo, so I went ahead and cut one out on my Silhouette onto some vinyl and stuck it to the shirt. I'm not fancy enough to do iron-on yet, so I literally just slapped some vinyl on there. Again, I'm not planning on these lasting forever. Then the boys wore jeans, and a long-sleeve tee-shirt under. Black gloves optional in your neck of the woods. :)
For the hats, I took black pipe cleaners, cut them in half, and just stuck them through the beanies. I did all the hair a little bit different. My son specifically wanted his all close together, like Kevin, because I guess Kevin is the tallest minion and my son is very proud that he is the tallest cousin. LOL. Here is a pic where you can see the hair a little bit better.
Unfortunately our event had nothing but POURING rain, so I didn't get the best pics of the minion costumes, but I'll try again on Halloween. In the meantime, hopefully this at least gives you an idea of how we did ours!
