Here's one with a hood.  I don't like the shape of the jacket as much but it looks like you could extend the collar up into a hood.  It might be easiest with the butterick pattern since it already has that extended collar.

I'm not sure of the size you are going for but here's a few that go up to size 20. 
McCalls 5060

Simplicity 4403 (up to size 24)  I've made this one and it turned out really cute - just be patient with the directions, they are confusing at first (I thought they left out a step) but it made sense in the end!

This one has the option of an interesting collar and is up to a size 22
Butterick 4665

Good luck!!

Does this look somewhat similar? 

I can't see the details of the original dress too well, but this may work.  I've made version A and look pregnant in it so I don't wear it but hope to be preggers soon!

An option with long sleeves...maybe completely not your style and could certainly not use the lace...

This jacket reminds me of Hepburn (I love her too!)

This could be awesome in a great plaid

I've made a couple of these and they are pretty simple really.  Actually, I think it was my first sewing project I ever did!  I would try to go a bit more toward a kilt if you want it to be knee length.  So a box pleat would certainly work. 

As far as cutting at the jeans, you've got the idea - just make it a little easier on yourself and cut out the actual seam.  There will be way too much fabric so sew through if you don't. 

Make sure the jeans you are using are pretty baggy, especially in the hips - you don't want to be walking around with the top of your legs restricted! 

Here's the last one I made (it was for a little girl)





About the pleats, I'm really not sure how they would work...If you have too much fabric in the insert it will just stick out straight forward.  I'll think about it a bit more...

It's possible that I'm not understanding the difference between the two types of corsets (though very interested in the difference!) but here's what I found...

Maybe this one?
#9764


This one seems a bit closer...
#9769


Or this one...

Because these are the same company, it's possible they are the same corset, but here's another

I've used this pattern twice - one of them lined and the other not.  It is a very simple pattern without the lining but still easy enough with the lining - completely agree with not lining a hood with a slick fabric.  If you are doing a lining, I found that it was best to just read the directions and trust them whether it sounds logical or not because it ends up working! 
What material did you use?  It looks so soft and comfy!
I did have to shorten the lighter colored one I made though because I wear the cloaks to ren faires and didn't want it dragging. 

not a great picture of the brown one but I made that one and the blue one as well.  I can't remember how they are supposed to be held together but I used eyelets and leather ties. 
I also made the leather bodice, white flouce blouse, purple skirt, leather belt and pouch, and belly outfit!  Yep, an addiction, I know!

Thanks everyone! 
I got the fabric from Joann's (pretty much my only choice of fabric stores!) and I used this pattern for help on the sleeve and front bodice piece.
 
I added a collar to the bodice, didn't use the facing piece for the front, but did use the back piece, and didn't use the ruffle on the sleeve.
Here's the drawing I worked from...

The pleats in the back of the collar and the back waist piece were actually because it was too big and wasn't staying up on my shoulders.  But, the pleats became my favorite part of the shirt!   

I love posting on this site - my family and friends tend to think my clothing in weird!  You all are great for the confidence!

Hi everyone!  I finished this shirt about a month ago and thought I'd post for a little feedback.  It's probably the best finishing work I've ever done as I flat felled every seam rather than using my serger and actually ironed everything as I went (usually can't make myself do that!)
But, it is my own design and I'm totally obsessing about it right now!

Let me know what you think - please?!

I agree with the cotton or linen - I made a medieval style dress for my senior prom and I used a medium weight cotton with a sheer sleeve.  I would avoid anything shiney because with that much fabric, it may end up being too much.  I'm not very technical when it comes to historical clothing - I make it quite a bit for faires and theatre, but I think natural fabrics would be the way to go. 

Here's the pattern I used for my prom dress...


I made thw brown one and it pretty much looked the same as the picture. 
One common mistake that people make when choosing fabric for these types of costumes is using stretch velvet.  I abhor the stuff, it doesn't drape well, it doesn't breath, and it looks awful! 

Again, something  in a medium weight natural fabric will breath, drape well, and look good! 
Another thought, make sure it is heavy enough because that dress will need structure and a fabric that is too light will not look right.  Also, while an upholstery weight would be too heavy (though not all are the same weight, so don't avoid that aisle) something that feels heavy when you are buying it won't feel so heavy when you are wearing it.  The dress is designed to distribute the weight of the fabric appropriately.  For example, my wedding dress probably weighed a good 15 pounds but I wore it all night without realizing it!
