Throat protection, with posture collar.

   When using lamb's skin, of the vegetable tanned variety, it will be very soft.  And easily deform to shape, so double layering for strength is needed.  Then felt is added before the outer double layer is added, for four layers of leather at the middle buckle, with the felt spacer separating the pair of double layers of specially ordered leather.

   This inside the collar felt, can be Nuno Felting.  Often used in the fashion industry.  Along with those layers of vegetable tanned lamb's skin, double layered slowly yielding to shape.  With buckle systems requiring steel lined holes in those straps, because of the extreme softness the leather will exhibit.

This is the link to the article to Nuno Felting, complete with referencing to other sources.

   And this felt can be made to a Crimson Red, to draw the eyes to the collar.  With the inner two layers being made wide for greater comfort, such as with a three inch wide or wider collar.  Along with from one inch up to two inches up from the lower edge, those outer two layers can exist.  With the breaking in process allowing a deforming of the wide inner double layer for comfort.  All while a felt separator helps distribute the force from, those outer two layers.

   The liner felt can feel soft like silk, even though wet felting can be used to create the spacer felt.  With spacer felt for preventing stresses from excessively thickly stacked lamb's wool, from having its fiber used to bind it such as paraffin coated flax fiber from ripping through it.  And these buckles will have a metal cylinder to roll across, instead of rub across the lamb's skin straps.

   Those lined collars can be silky smooth on the inside, because of applied use of felting.  And this will hinder the blood circulation reduction caused by, finger grabs and choke holds to the throat.  Along with reducing blood vessel constriction in the neck, because of circulation near the spinal column.  Yet vegetable tanning is for a special softness just like lamb's skin, with both together being a custom order.

A red cape, for use with that chain mail dress

   One option for material is, boiled wool.  Meant to be more durable and windproof, because fibers are felted.  Much like worsted wool has a durability level, yet fibers are different because of length, so the entire processing is different.  And felt is a different process than this.

This is about boiled wool, along with its common applications.

   While if avoiding chain-mail on the head, alternatives exist such as hard-felt with pieces of surface metal.  Along with Nuno Felting, acting as a liner material.  So as to create a wool to wool marriage, as a hard felt outside, with a Nuno Felt inside for padding.  Even though a less elegant answer would be cotton.

This is general information about felt, from a potentially biased place.

Hard felt has an application, while also holding a place in people's cultural identity.

   Not all felt, ends up as the Hard Felt, often used in the Bowler Hat.  Instead, the Nuno Felting is a process allowing fibers such as Merino Wool, to drape like silk.  So felt can be used as armor, with its own group of difficulties.  Yet will be study enough against most empty handed strikes.

   With one substitute for boiled wool being, velour of the natural version.  This velour comes in multiple weights, yet is used for ease of movement and a velvety appearance.  So is less restrictive than using Lyons Velvet for a dress, under the chain-mail dress, while supplying the black under the steel.

   Yet since a warm and casual appearance is generated by the velour, it is not the dress oriented material, known as jersey.  And jersey is not the outerwear for comfort, but would contrast with the chain mail dress resting on it.  So jersey cloth is for greater visual appeal.

   While I prefer comfort and softness, so for personal use what supports that chain mail would be velour fabric.  And greater visual effects, such as a sharper contrast with color would use, Duvetyne.  With that Duvetyne being a version of twill fabric, with a velvet like nap on one side.  So the denseness of twill fabric, with Duvetyne avoids the comfort level of velour.  For preserving my life longer, when the variation of chain mail dress, is made of welded stainless steel.

   This is the listing of the version of tweed, that would have the stiffness for formal dresses and suits.  And that black version of this Duvetyne will be entirely black, on one side.  So it provides more protection for the dress, used with the chain mail dress.  With that Duvetyne providing a cape that is black, with its outside being on the side with the nap.  Those in motion pictures use this for light control, while it is also listed as, commando cloth.

   For this homicidal application, both jersey and velour are not the preferred materials.  Instead Duvetyne because of it being a twill, combined with the optical quality provided by the nap, will be better.

   A thin light and stretchy material, for tights is known as Milliskin.  Also used in the motion picture industry for costuming.  By clinging to the body and allowing breathable contact, with enough concealment just like with, costumes for certain people playing the role of superheroes. 

   With near the body, Coolmax is a trade-name to a specially engineered polyester knitted fabric.  And those other brand names exist, but under clothing such as a full slip could benefit from these engineered characteristics.  It is not about the brand name, so a competitors fabric could be used.
