Product Insights
The Sun Halter Open Tankini from Simons (C$69) offers versatile styling through a removable halter strap that can be tightened for lift, loosened for comfort, or removed for a strapless look, paired with a permanently attached sun charm and a fixed front slit. Its stretch-to-fit fabric and adjustable features (removable foam cups, adjustable halter) allow the S/M/L sizing to accommodate a wide range of body types and create four different silhouettes. However, the design prioritizes aesthetics over pool durability: the nylon-spandex blend absorbs water and becomes heavy, standard spandex degrades after roughly 50 hours in chlorinated water, the fixed opening limits coverage customization, and the suit lacks chlorine-resistant fabric or UPF 50+ protection. Care requires hand washing or a delicate machine cycle, with after-swim rinsing and shade drying recommended to extend lifespan.
- Halter strap
Removable halter strap: tie tight for lift, loosen for neck relief, or remove for a strapless neckline.
Why this is supported
The product description specifies a removable tie halter strap. Tied tightly, it lifts the bust; loosened, it reduces neck strain; removed entirely, it creates a strapless bandeau neckline that shifts focus to the centre sun charm and front slit. This versatility also allows the wearer to avoid neck and shoulder tan lines. When combined with the removable foam pads in the soft cups, the halter strap gives two independent customization axes: the strap controls neckline and support level, while the pads adjust bust projection and concealment.
- Decorative details
Centre sun charm is permanently attached; front slit is a fixed V-neck cutout.

the sun charm is a permanently affixed decorative piece — it's not designed to detach, so there is no risk of it falling off in the water or getting lost in the laundry.

The slit centre opening is a fixed design element — it is an open V-neck cutout, not adjustable.
Does the slit centre opening allow for adjustable coverage, or is it a fixed open V-neck?- Fit
Adjustable halter, removable cups, and stretch fabric provide custom fit across S/M/L sizes.
Why this is supported
The halter strap is removable and adjustable, offering multiple neckline options:
Tying the halter tighter lifts the bust line while a looser knot eases neck strain, and the strap can be removed entirely for a different neckline or to avoid a tan-line, giving you three wear options from one top.
How this top fits across different body types — removable_tie_halter_strapRemoving the halter transforms the neckline into a straighter bandeau, highlighting the sun charm and slit. The built-in cups accept removable foam pads for adjustable shaping:
The built-in soft cups provide a natural shaping baseline; slipping the removable foam pads in adds projection and concealment — a quick swap that tailors the bust profile without an underwire.
How this top fits across different body types — soft_cups_with_removable_foam_paddingThese adjustable components, together with the stretch fabric, allow the tankini to fit across its three sizes:
Because the tankini is sized only in Small, Medium, and Large, its stretch-to-fit construction and adjustable halter and cups are what make the sizing work across body types, accommodating those who typically fall between numeric sizes.

Removable foam pads and adjustable halter adjust bust shape and support; two necklines yield four silhouettes.

How this top fits across different body types — soft_cups_with_removable_foam_padding. The halter strap further adjusts the bust line:
Tying the halter tighter lifts the bust line while a looser knot eases neck strain
How this top fits across different body types — removable_tie_halter_strap. Removing the halter changes the neckline to a bandeau, and combining each pad option (in/out) with each neckline creates four total silhouettes.
- Sizing flexibility
Stretch-to-fit fabric and adjustable features make the S/M/L sizing work across a wide range of body types.
Why this is supported
Research explains that the stretch-to-fit construction and the adjustable halter and cups are what make the limited S/M/L sizing work across different body types:

- Sizing inclusivity
S/M/L sizing accommodates body types that fall between numeric sizes.
Why this is supported
The S/M/L size range is designed to accommodate a variety of body types, as noted by secondary research:
its stretch-to-fit construction and adjustable halter and cups are what make the sizing work across body types, accommodating those who typically fall between numeric sizes
How this top fits across different body types — s_m_l_sizing_with_stretch_leeway. This is supported by the stretch nylon-spandex fabric (82% nylon, 18% spandex) which allows the top to conform to different shapes.
- Halter adjustability
Halter tie tightens for lift, loosens for neck relief, or removes for strapless.
Why this is supported
The removable halter strap offers multiple fit adjustments:
Tying the halter tighter lifts the bust line while a looser knot eases neck strain
How this top fits across different body types — removable_tie_halter_strap, and the strap can be removed entirely for a strapless look, giving three distinct wear options from one top.
- Cup adjustability
Soft cups with removable foam pads customize bust projection.
Why this is supported
The built-in soft cups can be customized:
The built-in soft cups provide a natural shaping baseline; slipping the removable foam pads in adds projection and concealment
How this top fits across different body types — soft_cups_with_removable_foam_padding. This allows the wearer to adjust bust fit without an underwire.
- Fixed slit coverage
Fixed centre slit opening limits coverage customization.
Why this is supported
The centre slit opening is a fixed design element:
The slit centre opening is a fixed design element — it is an open V-neck cutout, not adjustable
Does the slit centre opening allow for adjustable coverage, or is it a fixed open V-neck?. This means the amount of midriff exposed is predetermined and cannot be adjusted.
- Water performance

Why this is supported
The nylon-spandex outer is reported to feel ultra-soft and cool, but
It absorbs more water than other synthetics. Your suit feels heavier in the pool.

Standard spandex degrades after ~50 hours in chlorinated water; design prioritizes aesthetics over pool durability.
Why this is supported

- Durability
Nylon-spandex blend: absorbs water, degrades in chlorine, requires hand washing.
Why this is supported
The fabric is a standard nylon-spandex blend. As
Nylon dries faster than cotton but slower than polyester. It absorbs more water than other synthetics. Your suit feels heavier in the pool.
berunclothes.comFurthermore,
In our lab observations, standard spandex becomes brittle after just 50 hours of exposure, whereas chemically modified variants maintain elasticity for over 300 hours in both chlorine and saltwater.
foralltex.comThis means that
Chlorine, plus sunscreen and body oils, slowly breaks down standard spandex (elastane). As the elastane degrades, the suit loses recovery and starts to sag, bag and go see-through.
stretchhouse.comAs a result, care instructions require
We recommend hand washing in cold water with mild detergent and laying flat to dry to maintain the fabric's elasticity.
What are the recommended care instructions? Can it be machine washed or only hand wash?.
- Care
Hand wash cold and flat dry; machine wash delicate in mesh bag permitted.
Why this is supported
The brand's care instructions state:
We recommend hand washing in cold water with mild detergent and laying flat to dry to maintain the fabric's elasticity. Machine washing on a delicate cycle in a mesh laundry bag is also acceptable, but avoid wringing or bleach.
What are the recommended care instructions? Can it be machine washed or only hand wash?The nylon blend absorbs more water than polyester, prolonging drying time:
~4% regain (holds more water, dries slower)
changletextile.comFlat drying overnight is typical; wringing is discouraged to protect spandex fibers.
- Chlorine and UV
Chlorine and UV degrade spandex; after-swim rinse and shade drying extend the suit's life.
Why this is supported
Standard spandex in the 82% nylon, 18% spandex fabric is vulnerable to chlorine and UV deterioration. Lab testing shows:

Resists damage from sun, salt, chlorine and heat
llbean.ca, the Simons tankini lacks such treatment. The lining (90% polyester, 10% spandex) is more chlorine-resistant than the outer, so the interior structure holds up longer, but the outer fabric remains the weak point.
