Romper Muslin

I felt this was an interesting muslin because it incorporated not only a blouse, but shorts as well. What’s more, this romper isn’t supposed to fit like overalls, which would have been rather easy to fit. No, this romper is supposed to be fitted. After getting the muslin made up, I noticed that this particular look had a distinctly 50s vibe. Sort of a Marilyn Monroe feel to it. Very pin-up. So much so, that even Mr. S commented on it and said that it would be a knock out when made up in the right fabric – and this is not something that he ever says about any of my muslins. He’s more of an end result type person with my projects. Anyhow, let me share my thoughts on the alterations I did to get it to this point, and what needed to still be done after.

To begin with, I noticed that the romper had terribly short shorts. WOW! I knew that I would not feel comfortable with shorts that short, so I extended the shorts 3 inches before even cutting out the muslin. Next I widened the hip and waist because, according to standard size 12 measurements, my waist and hips are larger than those measurements. After these two things I cut the muslin and sewed it up according to the pattern directions.

After getting the basic skeleton, and trying it on, I found that the upper torso through to the hip was much to large. All of this area was taken in 1 1/4″ on each side! Next of course, the shorts needed a crotch depth adjustment. I also felt (rather dumbly, I might add) that if I did the crotch depth adjustment that I wouldn’t need a crotch length adjustment, even though I always need this because my inner thigh is rather large in comparison to most patterns. Still though, I didn’t do it and am almost finished with my final romper and can see that I could have benefited from a slight crotch length adjustment.

I think one of the reasons I thought I could go without one is because the pattern has you sew up the crotch area in reverse order than normal pants patterns. Instead of sewing the crotch from front to back (like most pants patterns I’ve encountered) it has you sew the crotch from right to left, or leg to leg. Make sense? I think this ends in a result that looks and hangs a little strange though and promptly changed that on the final version.

By the way, my new corkboard inspiration board also doubles as a pattern instruction holder (kind of like a recipe holder) and this is amazing because I always have a way of loosing and/or ripping the instructions when I get into a project. You know how it is, when the instructions get buried under your project and such.

Just a few muslin ramblings….



  • Tasha - That is going to be so freaking cute! Can’t wait to see the finished result. I love that the straps cross in the back. Smart idea about putting the pattern instructions on your board. You are so right, the instructions always seem to go hither and yon.ReplyCancel

    • Sunni - I love the way the straps cross in the back too! Much more than I thought I would. Kind of just makes the whole outfit!ReplyCancel

  • Casey - Looking good so far! I agree with Mr. S–this is going to be a knockout romper! 😉 I’m really interested in all the fitting adjustments you made; I’m on the cusp of starting a pair of trousers this week, and all this crotch-depth/length adjustment stuff has been filling my brain lately. haha. Mostly because I’m sure I’m going to have a lot to tackle, so seeing real-world examples helps me understand the fitting a bit more.

    Of course, seeing this is making me want to get back to making a better-fitting romper than the (two-day wonder) one I whipped up last summer. 😉 hehe.ReplyCancel

    • Sunni - Best of luck on your trousers, I’m sure they’ll turn out just peachy and brilliant! Once you get the hang of the alterations for trousers, they really are a cinch. As for the romper, I think it will be safe to say that I’ll be wearing it every single day. Don’t even know if I can bring myself to take it off for washings. Ha!ReplyCancel

  • Stephanie - Wow! Looks like it is going to be terribly cute!ReplyCancel

  • Ginger - Love the fit! It’s so flattering and fun! Can’t wait to see the finished product!ReplyCancel

  • Lauren - ok i feel really stupid now but how did i not ever think to hang my instructions on my cork board??? talk about the genius solution that also ends up being the most simple! haha!

    that romper is gonna look AWESOME on you! i mean, it already does, but i can’t wait to see it in the actual fabric 🙂ReplyCancel

    • Sunni - Why thanks! And the instructions on the corkboard just dawned on me after I had already battled loosing these. Sooooo much easier now! Hip hip Hooray!ReplyCancel

  • Curry Made - The muslin looks fantastic! Can’t wait to see the finished romper.ReplyCancel

  • Tanit-Isis - This is going to be super cute! I am terrified of rompers due to the whole body length/crotch-length thing… good for you for tackling it! 🙂ReplyCancel

  • Claire (aka Seemane) - Looking very cute Sunni :)!

    I was wondering though, are those the intended finished width for the shoulder-straps? Only, (and it’s only my personal styling-preference here) but they seem a wee bit wide on your shoulder’s at the front (by approx. ½”-¾”), yet they look look fine to me from behind (or maybe I need new spectacles LOL!).ReplyCancel

    • Sunni - Oh no, they are actually going to be about 1 1/4″ less in width. Just the muslin phase and I was much too lazy to thread mark the seam allowances. He he!ReplyCancel

  • Portia - Oooooh, Sunni! This is going to be good!!

  • Lizz - Yup – it’s going to be a knockout! I have some serious project envy going on right now – if only I had more time this week to work on a romper!ReplyCancel

    • Sunni - Thank you! I’m pretty impressed with it myself. Very excited to show off the finished version.ReplyCancel

  • Amy - Thanks for posting pictures of your muslin and discussing your fitting alterations. I find it so helpful to even just familiarize myself with the words, let alone get experience visualizing the pattern issues. I’ve never worked with a pants pattern, but I hope to soon.

    Also, just last night I was thinking about how much I love the tailor’s ham I got from your store. I’m sewing a little gown for my weeks-old niece, and I have no idea how I’d press something so tiny without the help of the ham. Thank you, thank you, thank you.ReplyCancel

    • Sunni - Thank you Amy! I’m so glad that the tailor’s ham is working so well for you! I love hearing from bloggers/customers who have used my products and are enjoying them! Best of luck with pants patterns. Once you get the general gist of how to do alterations for them they are not so bad. May I definitely recommend Pants for Real People. A must with pant alterations and what to look for.ReplyCancel

  • msmodiste - Oh, this is going to be so cute! I’ve only recently come around to the idea of rompers and now of course they’re everywhere… I’m trying desperately to decide if this is something I could pull off! I love the idea of a one-piece outfit, though. I hate coordinating!ReplyCancel

    • Sunni - Me too! Sometimes I can hit the nail on the head with coordinating, but gosh in the summer, its just too hot to do anything. I think I’m going to need at least one more just because of the heat.ReplyCancel
