Little Red Infinity Dress Tutorial

*Tutorial made by Melissa @ Sew Like My Mom for her win during the Red Week challenge.*

I made this little dress in about 3 hours and for under $20! I used some soft polyester knit I found at Hancock Fabrics for $4.99/yard. I got 5 yards, and with my 40% off 1 cut of fabric coupon, my total came to $15.87 after tax!! These dresses sell for upwards of $200 in stores, so I’m thrilled with my savings!

I found these dresses on Craftster years ago and have always loved them. I hadn’t thought about them in a while and was really excited when I decided on making one for my Red Week challenge. I read several blogs about how people made these and I was confused. All the directions were basically the same, but none took me step by step through the process. And no one’s math was the same! So using some from here and some from there, I was able to simplify them.

First, you need to do some measuring. To get the size of my circle skirt, I needed to measure my waist: 30″. I measured right at my belly button because that’s where the waist of this dress sits. To make that into a pattern, I needed to find the radius of a circle the size of my waist, so I divided by 6.28. You don’t need to know the fancy math, just trust me.

So, 30/6.28 = 4.7. I adjusted this to 4.5″ because my knit fabric stretches so it doesn’t have to be exact.

Then I decided on length of skirt and came up with 18″. In hindsight, I wish I’d gone about 4″ longer, but that’s just because I like to wear my skirts right below my knee instead of right above it. So decide length based on your personal preference.

To make your straps, you need to decide how wide to make them. To cover your bust, measure from your breastbone, over the fullest part of your breast, and to the middle of your underarm. Mine is 11″ (yes, I have gigantic hooters).

To determine strap length, you need to make them 1.5 times your height. It’s daunting, but doable! I’m 5’5″, which is 66″. 1.5 times 66 inches is 99 inches, but I just rounded up to 100.

So, got that? You need 4 measurements: waist divided by 6.28, length of skirt, width of straps, and length of straps.

To make your pattern, get packing paper, freezer paper, or a bunch of pieces of computer paper taped together. Start at one corner and measure down the first number you came up with for your waist. Mine is 4.5″ so I made a curved mark 4.5″ from the corner. Do this with the old pencil-on-a-string trick, or make a series of little marks and connect them with a line.

Then I measured 18″ down from that and made another line for my skirt length.

Cut out on your lines. You’ll have 1/4 of your circle skirt.

Now, keeping your fabric folded in half with selvages matched, fold the fabric in from the end so it’s doubled on itself. Place your pattern so the 2 straight lines match up with the edges.

Next, cut a waistband 10″ tall and the length of your waist you measured. So mine was 10″ by 30″. (In the picture mine is longer than 30″ but trust me on this! Make it the length of your waist measurement!)

Next you’ll have to cut your straps. You’ll need to lay your fabric out flat somewhere (and it’s 3 yards for me, so quite a bit of space!) to cut them all at once.

I kept my fabric folded in half so I could cut both straps at once. I took my ruled and placed pins 11″ apart, every 2″ the length of the fabric. Well, 100 inches of it, anyway!

Then I cut along the pin lines to get my straps.

Now for construction. A lot of people call this the 1 seam dress because it’s easy to do at once. I’d recommend doing it in parts, and wish I had.

Open up your circle skirt. If there are sides to your fabric, place the wrong side up.

Get your straps. They need to be overlapped a little, 3 to 5 inches is average for what I read. I opted for 5″ because I’m quite modest about my chest. So overlap the straps at one end and pin.

Take them to your skirt, and deciding a middle point, place the middle of the overlapped straps down.

I then pinned the straps from edge to edge.

This is where I recommend stopping and starting the sewing. Just sew the straps on then come back. If you’re daring, keep in reading to do it at once. I was just difficult to keep all the layers in the right place.

Take your waistband and fold it in half. Start in the middle of the front of the dress and sew the waistband on, all the way around to the beginning. There should be just a little overlap.

After securing the waistband to the dress, sew around the perimeter again, making sure everything has been included and reinforcing your seams. If you don’t have a serger, do a wide zigzag on your regular machine.

I took the waistband in the front and sewed the pieces together. I guess other people leave it V-shaped, but I wanted a more complete feel to my dress. I used black thread to show where I stitched because this part will never be seen.

(Please forgive the bunching at the waist. I made this dress to fit me, not my mannequin, and she hasn’t had 2 kids in the last 3 years!)

So this is what the completed dress looks like:

Then when you start wrapping it, you put it up over your bust one strap at a time.

To learn to tie it, I spent a lot of time on YouTube watching videos. There are a ton of them out there and they’re all super helpful.

    This is the most prefect dress! I have NEVER EVER made clothing..but..this tutorial makes me feel like I’d be able to do it :] Time to fire up my sewing machine and spend some time with my Gramma :]

    Thank you!!

    Sounds so cute! I want to try it. My concern is the skirt length…18″ sounds kinda short for someone pushing 50! I’m 5′ 3″, so I’ll probably take your advice and add at least 4″…might go longer, it’d be easier to shorten if too long than the reverse!

    I actually got lucky enough to score one of these dresses still in the original box and with a tying guide in a bag of handmedown clothes- and in my size! I have been wanting to make another one though in a different color so this tut is perfect! Thanks for sharing it!

    Looks amazing, can’t wait to try it. Only one thing – and this is very likely to me missing something obvious – but where you say “If there are sides to your fabric, place the wrong side up”, shouldn’t it be the RIGHT side? Sorry if I’m wrong, I just can’t get my head around how it works otherwise :-)

      I could be wrong, But i think the waistband is to lie on your stomach, and what you see as a “waistband” is from the straps being tied….

    This is positively adorable. I’m a seamstress so this looks like a great project for an afternoon! Thanks for the tutorial, I’ll definitely be giving this one a go! :)

    This is awesome! All of the ones that I find for sale are to short and I like mine over the knee also. “Sew” easy to understand :)
