Where in the world did you get the cake dress? Did you make it? Can i pretty please with a cherry on top have your pattern if you did i promise ill give total props to you and ill send you virtual cookies and warm milk. I really liked it.
First, the shirt section is almost a basic t-shirt, but instead of having two separate pieces for the front and back and sewing them at the shoulders, I just folded a piece of fabric in two and used the fold for the shoulder seam! The sleeves are two U shapes, with the ___ part of the U being the hem of the sleeve. If that’s confusing, it might help to look at a normal t-shirt and figure out the construction for that! If your fabric is stretchy enough (mine was actually hoodie jersey, just with the fluffy side out), you can just use a t-shirt with the fit you want as the pattern!
The skirt is just a half circle skirt (so basically, cut out a circle with 1/4 of your waist size + 1” for the waist, and then add however long you want the skirt and do a second half circle around that. Keep the base point for both and you can just swing your measuring tape with your chalk like a pendulum to make drawing the circle super easy) that I sewed to the t-shirt part!
The hood is just a really basic hood pattern, which you can get by copying a hoodie. (It looks kind of like a D if that helps, but you make two pieces) Make sure the bottom measurement is about 2” bigger than the measurement of your neckline (neckline allll the way around!) so that you can compensate for hemming and seams. I usually fudge these calculations a bit because I am the worst person to come to for measuring advice, as I usually just sort of go “eh, close enough” and then MAKE IT WORK. But yeah, I’m sure you’re more careful ahhaa… When in doubt, measure again! Also, for hoods, I tend to handsew them on with a hemming stitch (I think??) so that a french seam/the hem doesn’t stick out the back (this means you have to hem the bottom of the hood, though). It makes it a lot smoother, in my opinion!
Once the hood, shirt and skirt are all sewn together and hemmed (my fabric was a little stretchy and didn’t fray, so I didn’t have to worry about French seams. Fleece-y fabrics usually don’t fray, though you might end up covered in fuzzballs when you work…), you can start on the details! For all of the spots and stripes, I just cut out the shapes and pinned them where I wanted them. I would fold the raw edge under as I handsewed the pieces on (still with a hemming stitch). For the stomach spot, I left a gap on each side so that it could be used as a pocket!
For the nose, I did the same as with the spots above, but stuffed it so that it stuck out. I then sewed felt pieces cut like the nose and mouth to the nose mound!
The eyes are layers of felt. To keep the stitches from showing, I only stitch tiny, almost invisible lengths on the “right” side, but with longer stitches on the “wrong” side. This is the closest picture I could get to this sort of stitch, sorry!
The ears are four triangles (two per ear) made slightly taller than needed. Put two triangles right sides facing each other, and then sew two sides ( / and \ but not ___ ). Then trim the edges and turn it inside-out. Then stuff the ears and pin the excess of the bottom under it. This makes the ears 3 dimensional! I then sewed pink triangles of felt on top of the ears. Once your ears are done, pin them on the hood (make sure you’re careful and try it on a few times, or else you’ll have them uneven!) and sew around the base of the ear. Sew the ears on in a circle shape (and not just a straight line from one end of the ear to the other) in order to get them to stay 3D, perky and firm (instead of floppy and dog-like).
For the tail, sew a strip of orange fabric to a wider strip of white fabric, then fold it over (right sides together). Draw the shape of the tail you want and sew on the line (do NOT cut first, then sew!), Leave the base of the tail open so that you can turn it inside out after you’ve trimmed the excess fabric. Then, stuff the tail and pin it to your dress at the desired height! (I think mine is just above the area where the skirt meets the shirt) Like with the ears, it’s best to sew in a circle rather than a straight line, so that the tail will look more like a tail and less like a stuffed animal you pinned to your back.
I hope that helps!! I’m sorry I couldn’t give you a pattern, I’m pretty useless like that. Fortunately, the dress is basically just a bunch of super simply patterns stuck together, with all the superficial details just handsewn on top!
