Tonight C is Harry Potter (glasses he got from THIS awesome party).
D is Ron Weasley:
And Little Miss B is Hermione Granger:
With this Harry Potter lego sitting on the top of my sewing machine…
… I used Simplicity pattern 5512 as a guide for these 3 costumes. I greatly altered the pattern pieces, but it was a great starting point for me. 
After my kids figured out what they wanted to be, I looked at Harry Potter robes and ties online, only to find that they are pretty pricey. Buying one wouldn’t be bad, but times it by 3 and it’s too much for me! I made these costumes for about $15.00 each. Not as cheap as I had hoped, but the quality is better than what I would pay for online. If I bought the robe and a tie, I was looking at at least $35.00 per costume for any that were decently reviewed. 
I added a lining to the robes, and a pocket for their wands (ordered off Amazon—they make a cool noise and everything). Thanks to Sabra for helping me figure out how to line them!
The 3 Gryffindor crests I ordered on ebay for $9.00 total, shipped. They aren’t official, I’m sure, but they look great and my kids thought they were the coolest.
I really cheated on the ties and didn’t do them any sort of official way. I learned before when I made ties that they take a long time to sew the correct way. 
So here’s a little short version of how I sewed them. I traced a tie that fit the kids so there were two pieces. Not long, just a few inches longer than the top of the tie I traced. I cut strips for the stripes and made them kind of like single folded bias tape. Then I sewed the stripes on, placed right sides together and left a space to turn on the side near the top narrow area. I sewed around the edges minus the hole to turn, clipped the corners, turned, topstitched the hole, and ironed. 
I made a loop with the top part of the tie and topstitched down, then folded in half and sewed a couple stitches in the back to make it bunch. 
I made the neck band the same way as I do my bow tie neck bands and looped it through the ties. Easy and SO cheap with the cheap-o Walmart fabric! 
I sewed on an elastic hair-band to secure the robe closed, with two buttons on either side. 
And for the vests, I just bought a cheap sweatshirt or t-shirt from the thrift store ($1.00 each), cut the necks to a V, and sewed on gray double folded bias tape. Just a note: I liked how the sweatshirt looked much better than the t-shirts!
(Tomorrow I’ll show you what the hubs and I were. The kids were disappointed we didn’t dress up to go along with them, but we did dress as a “couple”.)
Haha! Adorable! Great job on the costumes!
Also, I really hope one of you was Voldemort. That would be funny. :)
Great job on the costumes! You’re kids look adorable and so much cuter than the actors.

Your robes look fantastic. We are also potter themed in our home, and I cracked up when I saw you did the same hair treatment. I love it!
These photos totally made me smile. Your kids look awesome, and the costumes are fantastic. Great job!
THis is the best set of costumes I have seen on the internet and off. Great job.
Great Job on the costumes! They look fantastic. The photos are such keepsakes. I hope they have a great time trick or treating!
LOVE the wand pocket! You’re so clever. J informed the that the one with C on the rock is the “coolest of the pictures”. It all looks great!
looooove these! amazing job. and the wand pocket – seriously? wonderful. my classroom is set up in four groups and each is a different house from harry potter.

Oh goodness! These are great! I can’t believe you made them. They look so professional!
Those are awesome! How perfect for your three kids! I can’t wait to see what you were :).
Awesome! These are Great!
These are awesome! Great job Christie. All the details are amazing and for $15 each…that’s really good.
LOVE the costumes!! They are so CUTE!
The costumes are great and I love the expression on Little Miss B’s face in the first photo!
Okay, those are probably the cutest group of dressed up kids I’ve seen this Halloween. I LOVE that they all wanted to be them together. So cute!!
Oh my word you went all out! I love these costumes! And I love that you went to Etsy for Gryffindor things. You have such talent.
wow, what amazing HP costumes
I love these robes! I’m going to make one for my daughter. I like the look of the fabric you used. Do you mind sharing what type you used? And does the pattern give instructions on how to add the lining? Thanks!
The fabric was just the cheap polyester lining fabric at Joann. The pattern doesn’t tell you how to line them, so I’m not much help there. You may be able to look up videos on how to line clothing and it may help. :)
