The thread band collar
Single-line band — discreet day-collar reading
A delicate single-line band, often with a small bow, knot, or charm at the front-center. Reads as decorative neckline ornament to most outside viewers. The most discreet day-collar render — chosen by many practitioners as a permanent stand-in for a removable physical day-collar. Single-needle fine-line. Sits at the base of the neck along the collarbone, or higher up the throat depending on neckline preference. Honest caveat: anterior neck skin is generally thinner and more mobile than torso skin, and very fine linework softens sooner here than on the inner forearm or ribcage.
Scale. Wraparound; line work approximately 0.1 inches thick
Placements. Base of neck · throat · upper chest line
The traditional neck collar
Bold-line collar with buckle or D-ring
A more declarative band — Traditional outline weight, often with a visible buckle, D-ring, or central charm. Reads as deliberate to most viewers. Sits at the base of the neck. Traditional or Neo-Traditional. Pairs naturally with a small lock-and-key motif on the front-center. Holds line weight better than the thread band over the long term because the heavier outline scaffolds the design — important on a high-flex zone like the throat.
Scale. Wraparound at 0.3 – 0.5 inch thickness
Placements. Base of neck · upper chest
The collarbone ornamental
Decorative work along the collarbone, no full wraparound
Ornamental linework that follows the collarbone curve — filigree, lace-referenced scrollwork, dotwork stippling — terminating in a small lock or central charm. Doesn't wrap the neck; reads as decorative chest-piece to outside viewers. Sits below most necklines. Three to five inches per side. Fine-line or dotwork. Works well as a discreet alternative for clients whose work or family environment makes a wraparound throat band unworkable.
Scale. 3 – 5 inches per side
Placements. Collarbone · upper chest · décolletage
The matched lock-and-key (asymmetric)
Lock on one wearer, key on the other — power-exchange coded
The classic D-s asymmetric configuration. One partner wears the lock; the other holds the key. In community convention, the key-holder is typically (but not universally) the dominant partner — community readers often infer this; outside readers usually do not. Inner-wrist or over-the-heart placement. Single-needle, one to two inches. Pair the design as a single appointment; don't split across studios.
Scale. 1 – 2 inches per piece
Placements. Inner wrist · inner forearm · over the heart
The matched lock-and-key (equal-pair)
Same image, two partners, no asymmetry implied
Plenty of couples — kink and vanilla — choose lock-and-key as a matching tattoo without the unilateral-ownership reading. Either partner can wear either half, or both wear the same half. The piece reads as commitment without encoding a power dynamic. The same design language as the asymmetric version; the meaning sits in the wearers' agreement, not the symbol itself.
Scale. 1 – 2 inches per piece
Placements. Inner wrist · over the heart · inner forearm · sternum
The self-collaring piece
Lock and key on a single body
A lock and key composed together on one body — sternum, forearm, or ribs. Used by solo practitioners, switches, people in poly configurations where there is no single key-holder, and clients who want the symbol as a self-claimed commitment. Reads to community viewers as self-ownership; reads to outside viewers as ornamental love-token. A genuinely common request — not a fallback for unpartnered clients.
Scale. 2 – 4 inches
Placements. Sternum · forearm · ribs · over the heart
The padlock over the heart
Single padlock — partner often holds the key
A traditional or illustrative padlock rendered over the wearer's heart. The partner often wears a matching key elsewhere — sometimes also over the heart, sometimes on the inner forearm or wrist. Two to four inches. Traditional, neo-traditional, or fine-line illustrative. Reads as a Victorian-romantic love-token to most outside viewers; reads as a community signal to in-the-know readers — clients can choose which audience the piece is for.
Scale. 2 – 4 inches
Placements. Over the heart · inner bicep · sternum
The bow collar
Ribbon-and-bow render, neck or wrist
A delicate ribbon rendered as a tied bow around the neck or wrist. Soft, ornamental, frequently chosen by clients who want the day-collar reference without the buckle or D-ring's weight. Common in CGL/Dd-aesthetic dynamics, where collar conventions tend toward pastel hardware, charms, and bows rather than leather-lineage iron. Fine-line. Honest caveat: ribbon line work softens faster than buckle work because the design relies on thin parallel lines.
Scale. Wraparound; bow approximately 1 – 2 inches
Placements. Base of neck · wrist · ankle · upper thigh
The collar-and-tag
Day-collar with a hanging name or initial tag
A collar around the neck or wrist with a small hanging tag. The tag often holds the personal element — a chosen name, an initial, a date, a single meaningful word. Initials, chosen names, or dates are usually easier to live with long-term than full legal names. Traditional or illustrative. Three to five inches at full neck scale, smaller at wrist scale.
Scale. Wraparound; tag approximately 0.5 – 1 inch
Placements. Base of neck · wrist · ankle
The Victorian filigree collar
Ornamental scrollwork — passes as classical jewelry
Decorative Victorian-era filigree rendering as the collar's structure — no buckle, no D-ring, just intricate ornamental linework that reads as decorative neckline. The day-collar reading is held privately; the piece passes as classical ornament to outside viewers. Fine-line, three-to-five inches across the front of the neck. The most discreet of the wraparound variants.
Scale. 3 – 6 inches across the front
Placements. Base of neck · upper chest · collarbone
The standalone key
Key as a piece in its own right — dom-coded or solo
Skeleton-key, antique-key, or Victorian-key designs as a standalone piece. Dominants and key-holders frequently wear the key alone, with no matched lock; solo practitioners and switches also choose the key on its own. Reads as a freedom or unlocking-potential motif to outside viewers (a long-standing standalone meaning in tattoo lit). Inner forearm, ribcage, sternum.
Scale. 2 – 5 inches
Placements. Inner forearm · ribcage · sternum · over the heart
The inner-wrist date and lock
Padlock with a commitment date underneath
A small padlock or collar-buckle render with a single date — a collaring or commitment date, a relationship anniversary, a ceremonial day — beneath it. Memorializes a specific moment without committing the wearer to a partner's full legal name. Inner wrist or inner forearm. Fine-line. Often paired with a partner-side render holding the key and a matching date.
Scale. 1 – 2 inches
Placements. Inner wrist · inner forearm · over the heart
