I’ve been excited to finally share this project with you, but mostly excited to finally see my sweet little girl on the outside and in this mermaid gown that I designed for her! I partnered with 
When I learned about the 
We’ve had a few weeks to try it out and the Smart Sock has become a part of our nightly baby routine. Bath + sleep gown + Smart Sock. Check Check Check, SLEEP. The sock links to an app on your Android or iPhone is designed to notify you from the base if the readings fall out of range. The sock doesn’t fall off and I’m feeling pretty well rested for a mom of a 3 week old! 
The base station is shown above. This is where the notification comes from and where the sock chargers. To stop the notification you just press the top of the base, which has a cute owl on it.
I totally recommend this product for all new parents looking for a little more peace of mind. Can’t buy happiness, but you can buy PEACE! (And sleep!) 
So as you’re knotting up your baby in this mermaid baby gown, you can rest assured that she’ll be just fine. 
This pattern is now available HERE in sizes Newborn to 18M! This makes a super cute shower gift. Wrap one up with a Smart Sock for a gift or use it on your own baby! I don’t see anything wrong with mermaid tails for boys, but if you want a basic gown with an elastic hem, there are instructions for that as well.
So let’s make one! (Or five!)

Helpful Tools:
-safety pin
Before you start:
-Use a 3/8″ seam allowance unless otherwise noted.
-Use a stretch stitch or zig zag stitch
Instructions:
Print out your pattern pieces and tape them together as shown below. There will be approx 1/2″ extra paper on each edge when printing on 8.5″ by 11″ paper. This pattern is also formatted for A4 printing.
Use the pattern pieces to cut:
-1 Front on fold
-1 Back on fold
-2 Sleeves on fold
-2 Tail lining pieces on fold
-1 front binding
-1 back binding
Start with the binding pieces. Fold both pieces in half and press. Pin the middle of the front binding piece to the middle of the front gown neckline. The raw edges of the binding and the raw edge of the gown will match up. 
Sew the binding to the front 3/8″ from raw edges. Finish seam allowance with serger or zig zag stitch. Press binding UP and seam allowance DOWN. Topstitch along gown neckline, stitching the seam allowance down on the back at the same time. Repeat with back gown piece and back binding. 
Lay the back gown piece on top of the front piece, both gown pieces will have the rights side of the fabric FACE UP. Match up the arm holes at the overlap marks. Stretch arm holes to match each other and baste fabric in place with a wide stitch. 
Finish edge of sleeve with serger or zig zag stitch. Fold under 1/2″ at the hem and press. Sew. 
Stretch sleeve to fit into armhole opening. Pin and sew in place. 
Repeat with second sleeve. Then fold the front onto the back with right sides together. Line up the bottom of the sleeves and the side seams. Sew all the way up and pivot at the sleeve. Backstitch at each end. Finish seam allowances. 
Almost done! The last step is to line the tail with the tail lining pieces. Start by sewing the two tail lining pieces together with right sides together at the center front and back with 3/8″ seam allowance. Finish the top edge (the straight edge) of the tail lining with serger or zig zag stitch. 
Open the tail lining and match it up to the RIGHT side of the baby gown. Right sides will be together. Sew around the bottom edges of the mermaid tail using a 1/4″ seam allowance. Trim the seam allowance with pinking shears or clip it with regular sewing scissors. 
Flip tail lining to the inside of the gown. Push out edges carefully and press well. Flatten tail lining and sew around the top of the lining piece to hold it in place. 
Turn your gown right side out and you’re done! 
Basic Gown Variation: cut front and back on dotted line and omit tail lining pieces. Assemble according to mermaid gown directions. Sew the side seams together and then continue following these directions: Finish the bottom edge of the gown with a serger or zig zag stitch. Fold under 3/4″ and press well. Stitch close to the raw edge all the way around the hem, leaving about 1″ open. 
Thread elastic through the casing with a safety pin. Sew elastic together and finish casing.

So sweet! Thanks for the pattern, I’ll be making a few of these even though my baby is much older. Everyone keeps telling us we need to try for another girl, maybe…I’d have plenty to make for her and this would be on the top of the list. Congratulations on your newest addition. There’s nothing like a new baby :)
Hi, is there a measurement box to make sure I have printed it out in the right scale? It looks tiny, but I quickly forget how teeny they are when they are new. Super cute pattern, right in time for a baby shower gift I have been delaying. Thank you so much!
Oh my goodness. This is so cute, I can hardly stand it! And what a cool product that I wish I had with my babies!
I love this fabric Art Gallery Recollection Knit c/o Raspberry Creek Fabrics I can no longer find it on this Etsy page do you know where else I might be able to find it? When will a bigger size be available? This is simply adorable, thank you for the free pattern.
Thank you!
Also I can’t seem to locate the pretty colorful floral fabric where is it from??
Adorable pattern, Kate! Baby gowns are my go-to baby shower gift and I’m loving the mermaid tail. Is this pattern for private use only, or can I make and sell gowns using this pattern in my Etsy shop?
I signed up to get this pattern and I received a pattern for an apron, is it possible to just get the mermaid pattern?
Where did you get your fabric? So cute. Cant wait to make this. Thanks
I absolutely love the patterns you post Kate! This one is adorable! I was so excited to try it that I used some knit jersey I had on hand. A bit of a mistake, the fabric was way too light. Perhaps warn your readers not to scrimp and use good knit fabric! Still, I don’t think my grandchild will notice the mistakes and wonkiness. LOL Thank you so much for this pattern and all the other ones posted and that I try to make. If the grandchild turns out to be a boy, I’ll call this a fish nightgown so as not affect the father’s sensibilities! :-)
what is A4 printing. mine did not print the whole pattern had five half pages
