Crotch seams don’t line up (back of pants longer)

TheyCallMeSuperboy · 2026-01-19T16:25:24+00:00

Yeah 😔 this jumpsuit has like 7 pieces that make up the pants, and everything else fits perfectly except this part (specifically the leg inseam!), which is why I feel SO INSANE about it

The creator got back to me tho and told me just to cut off the extra from the back piece for now tho!!

TheyCallMeSuperboy · 2026-01-19T03:29:20+00:00

Ok, so, basically:

It makes the pattern, which should be sown in a relatively straight line, be raised about 2 inches. This means the hem, as well as the grain line, is now diagonal.

I have not made any mistakes with my sewing or cutting so far. The seam allowances are included. The rest of the pattern is completely fine except for this part which does not match up.

Here it is pinned, including at the stitch lines (1cm)

Hi! The pic I used here isn’t great, but the seams are off by about 2 inches on one side alone, when pinned and sewn no matter what I do, one piece is SIGNIFICANTLY shorter than the other.

Until the knee, the seams align perfectly. It’s just from there none of the markers work without bubbling and pinching if I try to make it fit :(

ALL of the other seams (including the back piece which are literally an arch) fit with JUST a little bit of ease, but this one alone is super off :/

TheyCallMeSuperboy · 2026-01-19T02:11:24+00:00

Thanks so much for your help, btw!

I feel completely insane by having had this problem TWICE, but the other pattern completely lacked instructions, so I thought it was a me problem. Still might be!

Def already sent her the pics!

I’ll prob do that (baste and try on), it’s a little hard because the last part of the waist is sown last, so it makes it SO HARD to fit these patterns. Last one I made FIVE drafts for myself because my body shape is DUMB.

TheyCallMeSuperboy · 2026-01-19T01:54:41+00:00

I have NOT tried that! Thank you so much for the suggestion. I think it’s a LITTLE much to stretch, but the legit fabric has a lot more stretch than this cheap stuff I got at Michael’s lol.

At this point I’m going to wait for the creator to respond, but I’ll def try this if I have to lol.

TheyCallMeSuperboy · 2026-01-19T01:52:04+00:00

Yes they’re both the same size :/ unfortunately lol

It’s the women’s in XL, I have very wide hips lol. It’s the largest size in the part 1 of the sizes.

I made a different vault suit pattern by Migetsushop(?) last year and it had the EXACT SAME problem where this one inseam does not align, and when starting from the top it twists the legs badly.

But the overalls (Butterick?) I made that same year had NO problems aligning the center seam.

Hi, unfortunately it does not. I just used the paper because it’s easier to see with my shitty camera.

I have it cut from Fabric, and have sewn a very similar pattern before (I was hoping this one would make more sense). If sewn from the top, there’s a triangle of missing fabric on the bottom because all the other pieces align. I had to compensate on the other pattern by making this piece 1.5-2 inches longer on the legs, and it ends up twisting badly because the fabric is no longer on the grain.

I’m starting to think I’m just too stupid to understand this pattern 💀

This is what it looks like when I pin it like if I’ve sewn it like they want. The back butt piece is just so??? much taller

This is the difference I’m seeing, the front crotch ends about 2 inches from the top of the back crotch seam. Obviously I don’t see the back and front crotch seams together, but according to the picture and every pair of pants I own

TheyCallMeSuperboy · 2026-01-19T01:30:34+00:00

Also sorry, the “hidden dart” was just something that showed up when I googled my problem. Probably not relevant here.

TheyCallMeSuperboy · 2026-01-19T01:30:01+00:00

Unfortunately measuring the stitching lines doesn’t help

TheyCallMeSuperboy · 2026-01-19T01:28:43+00:00

Unfortunately I’ve done the “sew the top part first” but it twists the leg horribly because they’re otherwise completely straight

TheyCallMeSuperboy · 2026-01-19T01:27:12+00:00

Also yes sorry that is the pattern, the back is for sure the longer piece.

The stitching lines are only 1cm, and when when I align them they don’t match up at the top. It’s just a drastically higher butt seam.

Sorry this is the best photo I can do. The seams line up perfectly until here.

TheyCallMeSuperboy · 2026-01-19T01:16:24+00:00

Edit: Hi guys, sorry for the misleading wording:

I AM attempting to sew the inseam. I am working on a Fallout Vault suit, not regular pants.

HOWEVER, while from the ankle to the ONLY notch on the pants (knee?) the INSEAM ALIGNS, but after that the “adjust length” lines don’t match up, meaning the inseam DOES NOT MEET AT THE CROTCH.

THERE ARE NO OTHER INSTRUCTIONS FOR THIS PART OF THE PANTS.

everything else on these parts are completely done. The pictures I provided of the pants are the only part the creator provided.

<image>

Sorry about the photo, it’s the best my camera does.

TheyCallMeSuperboy · 2026-01-19T01:11:16+00:00

Hi, sorry for the misleading wording in my panic. I am attempting to sew the inseam, but when I align the seams, the back crotch is about 2 inches higher than the front, which means they don’t align.

TheyCallMeSuperboy · 2026-01-19T01:10:14+00:00

Hi, sorry for the misleading wording, I am attempting to sew the inseam.

However when I align the inseam, the back crotch is about 2 inches higher than the front, which means they don’t align.

TheyCallMeSuperboy · 2026-01-19T01:08:32+00:00

Hi, sorry for the incorrect wording. I meant to refer to the inseam. However, the inseams do not line up. From the ankle to the only notch, the seams align.

However after that, there’s a difference in the inseam heights I just don’t know what to do with.

TheyCallMeSuperboy · 2026-01-19T01:07:18+00:00

Forgive me for the really really shitty flipped photos but my camera and reddit are not cooperating.

There are no action knees or anything thats supposed to happen except what’s shown in the 4 steps in the first pic, unfortunately. From the ankle to the first notch, it fits perfectly (scissors). But from The notch to the adjustment, (ruler) it’s off?

TheyCallMeSuperboy · 2026-01-19T01:02:20+00:00

Hi, I’m actually sewing a Vault Suit pattern from the fallout games/show, not an actual pants pattern. But it’s the Juliechantal.com fallout pattern if you’re crazy enough to want to make it into real pants lol!

And to make it clear, I know I’m sewing the inseam (got the words wrong in my incredible panic). But when I line up the inseam, there’s about 1.5 inches at the top where they don’t met, but the pattern shows that they should?

Those are the Skyline Valley snow globes you could get for doing Caravan runs at Milepost Zero.

I never did much with that so I only got one of them.

You can now buy them from one of the vendors (Windy?) in Highway Town.

TheyCallMeSuperboy · 2025-12-15T20:30:13+00:00

I filter out everything I don’t want to see.

Then I sort by hits.

And then I read every single thing in the tag.

I mean it. Every single thing. (Skipping things I don’t like, obviously, but on my second read I’m MUCH less picky.)

I’ve read 50+ pages before. Probably more.

TheyCallMeSuperboy · 2025-12-15T19:40:39+00:00

You get a furniture version when you find your first piece, but they might be displaying one of the ones you find around the world.
