the only mccalls pattern I could find with that number is for a toddler's short set...
Picture please?
Goodness, I apologize! I did have the wrong number - it's actually Simplicity 5386, the Matrix coat pattern. http://sewing.patternreview.com/cgi-bin/patterns/sewingpatterns.pl?patternid=6120

I'm terribly sorry. Good luck!
I've just spent the last three days trying to sew a Horrible coat for my son (age 5) to wear when he goes with friends to see Igor on Friday. I had just declared the project "Temporarily Canceled Because It Ate My Brain", but maybe I'll give it another shot tomorrow knpw that I know there's hope...
Thanks for the post!

Good luck! I'm not sure how well this will scale down (this is an adult-size pattern), but if you can get the general shape right the principles are the same.
wow, so comprehensive! thank you for the instructions! i've never sewn in my life, but my husband was a fashion design major, so i'm going to make him help me. bwah hahaha!

really, thanks a lot. i never would have had a chance before; this walkthrough helps a lot.
Glad to help, I wish you luck!
This should go in the community memories or something!
Excellent thank you so much for this and your hard work!
No problem! Let me know if you have any questions. :)
Dollar stores have started to carry brow craft paper. 3 feet by 14 feet long. While not as wide as the newsprint, it is sturdier and requires less taping.

Making the coat

Would it be possible to commission you to make and sell me a coat at a reasonable price?

Re: Making the coat

It would depend entirely on when you need it by. I'm a college student with two part-time jobs, so I wouldn't be able to have it done by Halloween. I could arrange to have it by the end of November, though.

My commission fee for this coat is $60 with an embroidered caduceus, or $54 with an iron-on one. Raw materials cost about $30 for the white coat, $35 for red (white twill is cheaper where I can buy it). You would also need boots, gloves, and goggles, and prices vary depending on where you get them. If you're still interested, let me know!
Does this pattern have side splits? :)

Sewing directions:
8. Sew narrow hem on front left below waist. Use only the 5/8” seam allowance.
9. Sew narrow hem on back left and right below waist. Use only the 5/8” seam allowance.


Thanks for all your work on this and sharing it with us! Looking forward to your finished project! I've started working on this project, but do not understand your instructions for the collar. Is there any length added to the original pattern? How do the markings match up with the body of the jacket?

Thanks again!

Re: Collar?

I'm afraid can't explain it much better than I did in the Collar section. The final collar will be approximately 2 to 2+1/2 times the length of the original pattern piece. I suggest that you read over the instructions again and match up each of the instruction steps to the pictures.

The only match-up markings you put on will be the ones pictured here, on the far right side of the collar and its mirror-image mark.

Please let me know if you still need more help!
Thanks for posting these! I've got a question about tracing the back section. I'm not sure if they've changed the pattern or not, but mine has a shaped back seam and extra fabric to hem the slit in the back. Should I just match up the top of piece 4 and the bottom of piece 4 and use the straight line of the CB fold instead of following the curve of the pattern piece?
You took the words right out of my mouth.

Good luck!
Any chance to see a completed coat picture?
Very regrettably, not yet. So far I've only made a mockup (which uses fabric too ugly to see the light of day) and cut out the real fabric. I'm a college student, and schoolwork has been rough in the last month. I'll have it finished before Halloween, though, because that's when the commission is due.

I'll be sure to post a new entry in DrHorribleDress to let everyone know when I have pictures up!
To monkeynamederic:

I tried to reply to your message, but you have your messaging privacy turned on so I have to answer here.

Unfortunately, I am not able to take any commissions for this coat for Halloween this year. I am a college student, and right now I'm studying hard for midterms in addition to working two part-time jobs. We could talk about a commission for later in the year, or definitely for Halloween 2009, but as much as I'd love to I can't make you one in time this year.

If you know any friends who can sew, you could always refer them to this pattern and ask them to make you a coat for this Halloween. :)
Oh, heh. I figured as much.

Thanks for responding!
Thank you so much for posting this! I'll be starting on a lab coat for my hubby in the next couple of days, and this will definitely come in handy ~ and luckily I already own that Matrix pattern! Score! :D
Good luck! Let me know if you have any questions.
Looks great!

14. Sew sleeves to jacket, matching markings and gathering where necessary.

Oh, if only it were actually that easy! Haha, sleeves eat my brain.

Very nice job, though! Thanks for sharing all the in-progress pictures!
Congrats on the finished product! About how many hours total did it take?
Glad you asked! Fortunately, I posted this in my own LJ so I could remember later.

2 hours - pattern creation (including writing all the stuff -- it will take you guys a lot less time)
2.5 hours - mockup
.5 hours - cutting out fabric
5 hours - coat construction
1 hour - caduceus embroidery
.5 hours - ironing

This includes taking breaks for snacks and changing the movies I was watching. :)
Oh hay! I know him! (He who sports the costume.) : D
This is actually really helpful. My brother has me making him a Dr. Horrible costume for Halloween, so I'll definitely be using this. Thanks for posting it. ^_^
Did you hand embroider the insignia on the pocket or did you get it somewhere else?
I embroidered it myself. It took me a little under an hour.


Webstore canceled my order for a labcoat. This looks my only option as every medical supply store in the greater Los Angeles area doesn't have anything remotely close.

Of course, I don't have a sewing machine. Or skills.

Any amateur seamsters in the area want to make some dough?

Re: Argh.

ive been told that dentist coats are similar corse w those you'd have to add some material to the bottom to lengthen it but that's not a big deal
I wish I'd found this earlier.
now I'm trying to buy a lab coat from somewhere in england which is scheduled to arrive ON halloween.

Anyone out there?

Okay just in case anyone is as insane as I am and is still trying to make there costume as late as I am .. Is anyone and I mean ANYONE willing to take photos or and or scan or something the pattern? Because I do not have time to order it and as I live in the middle of NOWHERE it's impossible to just go to a shop and buy it O_o .. I'm desperate .. Anyone? .. .Or even just step by step measurements of each piece with little picto-diagrams? O_o I will wait ...

Re: Anyone out there?

well, I'm trying as late, but I haven't got the pattern yet.


I searched all the stores for a mad scientist lab coat and couldn't find anything. your coat however is great and these instructions were very informative. Even when I printed them off and some sentences went missing between pages. now All I need to do is sew on buttons or clasps I'm thinking clasps.

Just adding my note of thanks for this page. You saved me a ton of time and mucking around. All in all I just followed your instructions and came out with a really decent lab coat.

Awesome, thank you so much.
This is a really great pattern and directions! I've never used a machine before (sewed a Jedi cloak by hand..) but I want to try it out. If it all goes askew, are you still willing to do commissions? Would be wanting this for July.
Sure! Just let me know 6 weeks in advance. Sometimes it takes a while to get the materials in the mail (as well as mail it out).

Tips for making a better "draping" lab coat

For all those aspiring "Dr. Horribles", I have a few tips that will make the button placket of the coat "drape" better, as well as make it that much more durable. You will need some medium weight, fuseable interfacing in addition to the regular fabric (the interfacing is quite cheap, and is used to partially fuse two pieces of fabric together, to keep them from separating without stitching, which could ruin the look and the "line" of the garment, in the final product. Take the pattern for the front facing, use the straight edge that comes down from the shoulder point as a "fold" line, and cut a doubled facing panel (it'll look like a short version of the front, without a neck hole). Then cut a single facing panel as previously instructed, as well as two facing panels out of the interfacing. Set the single facing panel and one of the interfacing panels to the side for now. Fold the doubled facing panel, correct sides of the fabric out, with one of the interfacing panels in sandwiched in between. Run a 1/2" stitch down the length of the fold. The interfacing is now sewn in the middle of this now doubled facing panel. Before you sew this to the back, iron the facing panel with the cotton setting (with plenty of steam) so the interfacing will "fuse" the two halves together even more. Sew this now doubled front facing as previously instructed.

Now, take the second facing panel, line up the interfacing with it, and pin the entire bunch to the wrong side of the front panel on the top right part, lining up each corner, making sure that the interfacing is one of the outer layers. Sew (1/2" seam) around the shoulder, arm hole, and down to the edge of the facing panel. Turn the lot inside out, trimming and tweaking where necessary, making sure that all corners are fully turned out. Once that's done, press this side, again using the cotton setting on your iron, with plenty of steam. Give another 1/2" seam down the entire edge (this being one of the best time to make a "finished edge down the entire length of the front panel).

This will give the coat a better "drape", as well as provide more structure for the buttons and buttonholes. B.T.W., if you happen to have an automatic buttonholing function on your sewing machine, learn to use it. It helps so so so much. No need for guestimating your buttonhole length, one quick step, and you have a pretty damn good buttonhole in about 1/10th the time of handsewing the holes (and that's being either slow on the machine's part, or a virtuoso with a "sharp". Anything else, and I'll post it here.

Happy sewing, and may your bobbins never jam or break the thread.

Re: Tips for making a better "draping" lab coat

Any help anyone needs in understanding these directions, please ask. Or, just ask someone who is decently experienced with a sewing machine. They will understand what I am trying to do here. Maybe even improve things.
