Sketches for Rey

Fitted gathered bodice, sashes securely attached to base.  Belt or sash at natural waist.
Skirt is very gathered and made from same fabric as over-sashes, with lining underneath.

Most like original costume.
Shirt under with short dolman sleeves. Shirred sashes attached at shoulders only, and tucked into belt.
Skirt is same fabric as shirt, but slightly darker, mermaid style.  Leather belt.

Most "upscale" version, I think.
Fitted sleeveless bodice under, but sashes are loose and flowy over.
 Large belt can be leather, but does not have to be.  Belt darker color than rest.
Skirt is same fabric as under-bodice, slightly darker than sashes.
The above sketch also introduces the concept of Rey's staff that she is holding in a lot of the promo pictures can be made out of Lego. 

 This would open up the possibility of Uhura being able to have an Enterprise clutch made out of Lego instead of a Lego Comm badge, which might be cooler.

Also close to original costume, Cotton or other natural fiber shirt under, very short dolman sleeves.
Sashes attached at shoulders and secured at waist.
Leather split belt placed below natural waistline.
Skirt is same material as shirt, not too full.
Fitted gathered bodice, fitted strapless under-bodice, more as security liner than important part of design.  Sashes maybe made of more sheer fabric than in movie.
Belt rides Higher than natural waist.
Skirt 3 layered full circle (even though sketch looks like only one layer), 2 sheer layers and a solid liner,
flare begins at hip poiut.
