Butterick B6051 deserved an immediate encore, so thatโs what I did: sewed one right after the other. Iโve had a crush on this dramatic maxi dress for a while, and this summer, I knew it was time to get serious about our relationship.
Join me, wonโt you, as I add two bold maxi dresses to my wardrobe!

Pattern Description
Butterick B6051 is a sweeping, pullover maxi dress with four views. I sewed view A, which has a surplice bodice, full skirt, and no sleeves. As you can see, I sewed two versions of A: one with a back waist tie (navy with flowers) and one without a back waist tie (black bodice). I first saw this dress made by the Stitch Sisters, and itโs been on my mind since then. When Joann ran a super sale on Big 4 patterns, I was all over this dress pattern.


Pattern Sizing
The pattern comes in sizes 8 (31 ยฝ inch bust, 33 ยฝ hip) to 24 (46 bust, 48 hip). To pick my size, I practiced some flat pattern measuring. (I measured the flat pattern pieces from seamline to seamline.) Check this out…
My Body Measurements vs. B6051 Flat Pattern Measurements (in Inches)
Size 8 Envelope Body Measurements | Size 8 Flat Pattern Measurements | Ease in Pattern | Erinโs Body | |
Upper Bust | 31 1/2 | 35 | 3 1/2 | 32 3/4 |
Waist | 24 | 29 | 5 | 27 3/4 |
Hip | 33 1/2 | 39 1/2 | 6 | 39 |
You can see thereโs a lot of ease built into this dress. I used my bust to pick my size (8), because waist and hip enlargements are easier to make vs. bust shrinkenings. When you start playing around with bust adjustments, armholes can get wonky. RELATED: How to Make a Full Bust Adjustment on T-Shirts (No Darts)
I was making these dresses in very stretchy fabric, so as long as I had SOME ease around my body, the dress would fit fine.
From the waist to the hip in the skirt, I graded to a 12. My full hip is 3 ยฝ inches lower than the patternโs full hip. I measured the flat pattern piece at this lower hip spot specific to my body and concluded that a size 12 hip would give me enough ease in the skirt.
Many sewists who shared this dress on Instagram noted that it had a lot of ease (and their pictures confirmed this observation). If I had gone with the envelope-recommended size based on my body measurements, where I chose a size based on my largest measurement (my hip), I would have sewn a size 14.
The finished upper bust measurement (including ease) for a size 14 is 39 ยฝ inches โ 6 ยพ inches larger than my body! Think of the bust adjustments it would take to size down! UGH. Flat pattern measuring definitely saved me from headaches. Itโs all about ease, guys, especially when it comes to Big 4 patterns.
Because I was sewing a size that varied so greatly from my body measurements, I made a muslin of the bodice. It fit great, and I went ahead with the fashion fabric.


Fabric Used
I used stretchy, slinky polyester ITY knits I bought at Vogue Fabrics in the Chicago suburbs. This type of fabric has a bit of bounce, and itโs great for a maxi-length skirt. Polyester can be hot to wear, but when itโs matched with a swishy skirt and sleeveless top, you donโt have to worry about overheating.
The navy flower knit has more drape than the green diamond knit. Navy flowers has more folds in the skirt vs. green diamonds.
The solid black bodice is an athleisure knit from Joann, and it was not part of the plan. I had cut out green diamond fabric for the bodice, taking great care not to end up with Boob Diamondsโข. As I sewed the bodice on my serger, my big dog, who was sitting at my feet under my sewing table, moved her big butt onto my serger foot pedal. You can guess what happened next โ a runaway line of serging and a lot of cursing.
I had to come up with a Plan B to replace my ruined green diamond bodice. I puttered around my neighborhood Joann for a replacement fabric and landed on black. I like the top-and-skirt effect of the black and green diamond fabric combo. Whatโs more, the green now is farther from my face, and I think thatโs a good thing, because green often is hard for me to wear. (But I do it anyway, because pretty fabric is pretty fabric!)
I learned a hard lesson sewing this pattern: Donโt let your dog sit under the sewing table when youโre sewing, especially if sheโs a big gal whoโs hard to move.

Sewing Tips for the Butterick B6051 Dress
Build a Support System
Even though the instructions didnโt call for it, I stabilized the shoulder seams. I used nylon tape because itโs lightweight and doesnโt create bulk. Shoulder seams of stretchy knits are prone to becoming misshapen over time. Stabilizing seams helps stitching thatโs under stress win against gravity and wear and tear.
The Butterick B6051 instructions DO call for inserting quarter-inch elastic into the seam allowance of the waist seam. First you sew the waist seam. Then below the waist seam โ approximately ยผ inch to โ inch IN the seam allowance โ you sew another line of stitching, leaving a gap in the stitching about 2 inches wide. Next you insert a strip of elastic into the gap and work it through the casing. Finally you sew together the ends of the elastic and sew shut the gap to close the elastic casing.
The waist elastic helps hold up the skirt and take some of the stress of the mass of the skirt off the shoulder seams (another good reason to stabilize the shoulders!). I forgot to add the elastic to the navy flower dress; I serged the waist seam and thereโs no seam allowance for an elastic casing. I did remember elastic for the black-and-green dress, and it definitely helps carry the weight of the skirt. I need to figure out a way to add elastic to the waist of the flower dress! Suggestions?
Experiment with Raw Edge Finishes
So, these dresses took me a couple weeks to finish, which is a long time for a pattern of this relatively low complexity. I got caught up in testing finishes for the armholes and neckline.
The pattern calls for turning over the neckline and armholes and stitching down the raw edge. I wanted a finish with more polish, so I spent multiple days experimenting with the blind hem on my serger. Iโm not saying it canโt be done, but I was not satisfied with my sergerโs blind hem. In my opinion, the blind stitching was too visible, uneven in length, and not flat on the right side. (This failure almost assuredly is user error and inexperience!)
I think if I had more seam allowance to work with the blind hems would have turned out better. My instruction manual recommends hems of 1 ยฝ to 2 inches, and I was working with โ inch hems. I also think blind hems on curves are tricky, too, and the armhole is almost all curve.
After I gave up on the blind hem, I tried following the pattern instructions for the neckline and armhole finishes (turn and stitch). I had a heckuva time neatly pinning down the raw edge so it didnโt twist. Plus, this finish still felt too โrawโ to me.
Finally I went with sewing strips of fabric to the raw edges, turning the strips to the inside, and topstitching the strips. (This was my first instinct for finishing, and I should have stuck with it!) It was easier to keep the strip-armhole/neckline seam from twisting (vs. turn and stitch). There still was some twisting while sewing around curves; I should have used more pins and gone even slower when topstitching. Reducing the presser foot pressure probably would have helped, too. To finish the raw edges of the strips, I serged them off just past the topstitching.
The instructions have you sew the bodice side seams (to make a circle) before turning and stitching the armholes. I finished the armholes first and then sewed the side seams, because sewing in a line is easier than sewing in a circle. I wonder, though, if I couldnโt get an even better armhole finish if I sewed the side seam and finished the armhole more like I would sew a knit neckband. Definitely something for my next B6051 dress!
I could see B6051 becoming a staple dress for me. Itโs fast to sew after gathering the bodice. View D would be hyper fast โ the front of the bodice is one pattern piece (vs. two) cut on the fold. I also might have fun with the skirt length and sleeves. Wouldnโt flutter sleeves look pretty on this dress?
Over to you: Whatโs your favorite finish for raw knit edges? Would you have turned and topstitched? How do you feel about maxi dresses — in general and to sew and wear? Please share your thoughts in the comments!
Great looking maxi dresses!
Thanks, Linda! I love wearing them.
Oh so so pretty! Thanks for sharing! I saw your initial review on Pattern Review!
Hiiii, Barb! So glad you stopped by from PR.
Hi Erin,
Beautiful dresses and they do look comfortable and great for summer weather! Thanks for sharing your info here and on Pattern Review. I’m about to attempt this pattern and just want to confirm that I should be using the flat pattern measurements marked on the pattern and comparing it to my Upper Bust measurment (that is the area above my full bust measurement which is right below my underarms) to help gauge which pattern size to use? I will probably be gauging to one size up to accommodate my fullest hip measurement. Did you cut your “strips of fabric” on the bias, to use on the neckline and armholes. Thank you!
Hi, Judy! Thanks for reading. I would actually measure the paper pattern pieces using a flexible tape measure, just to be sure. I’m kinda paranoid that way.
Yes, the high/upper bust measurement is under your armpits, like this: https://images.app.goo.gl/VDR76rrLgadZDgd47. And you should choose your size based on your upper bust measurement, NOT your hip measurement. It’s MUCH MUCH easier to grade up in a skirt vs. grading down in the shoulders, especially with this pattern.
And – the armhole and neckline strips were cut on the crossgrain, not the bias. The crossgrain was plenty stretchy for this stretchy fabric.
LOVE the results of your work, the dresses are beautiful and fit perfectly!!
Thank you! It’s a great pattern.
Love your dresses! I have made a toile, and am happy with the fit, finally!
Questionโฆ
Does your pattern have a piece #6-skirt front? My pattern has 2 sheets that are duplicates and I have piece #7, skirt back, but no piece #6. For my toile, I just cut 2 skirt backs, and it seems to work.
Thanks so much!
Hi, Jill! I dug out the pattern and can answer your question.
Yes, my pattern had a skirt front – pattern piece #6 for views A and B and pattern piece #14 for views C and D.
Looking at the pattern piece illustrations as featured in the instructions, the front skirt pattern piece (#6) doesn’t look different from the back skirt pattern piece (#7).
FWIW the front skirt pattern piece for views C and D (#14) is a little wider than its back counterpart (#15). That’s probably because the back waist is usually narrower than the front waist.
Hope this helps! This is such a good pattern. Have fun with it. What’s your intended fabric?
Thank you so much for your reply! I will just make do with the back skirt pieces.
Happy New Year!
Jill
NP, my pleasure!
