Our next cosplay pattern is just in time for last month’s release of the newest Fantastic Beasts movie! Inspired by the character Newt Scamander, the Hydrus pattern is perfect for anyone looking to add a little magic to their wardrobe! We’ve added clever details like functional patch pockets with faux flaps, and a contrasting faux leather collar stand. Take advantage of this great pattern and make it your own! Or try one of Mood Fabrics’ wool coatings to make this an intriguing addition to your winter coat collection!


Fabrics & materials used:
- 4.5 yards of Italian Anthracite Faux Brushed Wool Coating
- 3.5 yards of Blue Nights Cupro Plain Dyed Certified Vegan Fabric
- 1/4 yard of Black Fashion Weight Faux Leather
- 1pk of Dritz size 45-1 1/8″ Half Ball Covered Buttons
- 1 Antique Brown Leather Buckle 3″
- MDF100 – The Hydrus Cosplay Sewing Pattern (free download below!)

Here’s how to sew:
The seam allowance in this pattern is 1/2″ unless otherwise stated.
Step 1
With right sides of fabric together, pin backs together and sew down the center back seam. Press seam flat.
Step 2
Pin fronts to the back at side seams and sew.
Step 3
Before you sew the sleeve seams you need to attach your cuffs. Pin cuffs to sleeve opening then fold under top cuff edge and top stitch.
Step 4
Finish sleeves by sewing the underarm seam.
Step 5
After you apply the fusible to your facings, pin your facings to your front pieces and stitch. Turn facings and press. Sew shoulder seams and press. Set in sleeves.
Step 6
Mark pocket placement on fronts.
Step 7
With right sides of pocket pieces together, stitch along the edge leaving a small opening for turning pocket right side out.
Step 8
Topstitch pocket and close opening. Fold down the top of pocket creating the faux flap and stitch in place. Pin pocket to coat and stitch in place as a patch pocket.
Step 10
Pin faux leather collar stand piece to the under collar and sew in place. Apply fusible and press seams flat. Pin collar facing to under collar and stitch along sides and top. Pin collar to neck opening and stitch in place.
Step 11
Attach belt loops to coat before setting in the lining. Set in the lining attaching it to the front facings and sleeve cuff opening.
Step 12
Now finish up all the end bits like covering the buttons and your buttonholes. Use the guide from the package if needed. Complete the belt and hem the bottom. The great thing about the Hydrus Coat is that it’s a great base for you to make it your own. Whether it’s for cosplay or to rock as a statement piece!

This is fabulous. Can’t wait to try it when I’m more experienced.
Thank you for having so many size options! I’m a 24/26 and am going to tweak this to cosplay Caleb, from Critical Role. I’m so excited- got the pattern printed and cut and am about to make my modifications now.
Woah, that’s awesome! I’m a new Critter, and I’m altering this coat to cosplay Mollymauk! All the best with yours.
Thank you, Mood writers, for sharing so many great cosplay patterns with us!! And for free!! I’ve found it SO helpful as a cosplayer who doesn’t have a super deep knowledge of drawing up my own patterns to simply adapt the ones you guys have on here. Right now I’m eyeballing this coat for a genderbent cosplay of the Fourth Doctor I’m planning to make this year. I need to do some research on how to change some of the seams around, but I think this could make a great base pattern! 😀
This is fantastic coat pattern. Making a TF2 Medic costume with a few modifications of the front for my son and he is absolutely thrilled by the look and fit. Thank you Mood!

Beautiful, amazing pattern! Just finished making my red wool coat and it’s easily one of the nicest things I have now! Only revision I would suggest is to attach the front pockets before attaching the front panels, as I found trying to maneuver the entire coat in my machine was very cumbersome. If I had the pockets already attached it would’ve been much easier.
Is the seam allowance included in the patterns?
Yes, a 1/2″ seam allowance is already included! 🙂
If seam allowance is included in the pattern can the pattern and the blog post get an update stating that?
I wouldn’t have known without reading this comment.
Thank you, Hecks! We’ve updated the post. Happy sewing!
Patron grati d abrigo
Adoro!!! vou fazer esse final de semana!
Thank you so much,,
Hi! I’m wondering if I can have a bit more explanation for the part where you attached the cuffs. Is it right sides together? Or wrong side of sleeve to right side of bottom of cuff and then when you fold it up the right side is showing? Sorry, I’m so confused. Thanks!

Hi, I’m making this coat for a Hange Zoe cosplay but I don’t want the collar to be high, I just want it to lay flat. What should I do? (sorry for my bad english)
