What are the exact waist and hip measurements for each size (S, M, L) of this high-waist bikini bottom?

According to Othersea's updated size chart, the waist and hip measurements for each size are: S (waist 27–28.5 in, hips 37–38.5 in), M (waist 29–31.5 in, hips 39–41.5 in), L (waist 32–34.5 in, hips 42–45.5 in).

Is the recycled polyester microfibre fabric chlorine-resistant and suitable for frequent pool use?

The recycled polyester microfibre fabric is not highly chlorine-resistant—prolonged chlorine exposure can damage the bikini. For frequent pool use, we recommend rinsing immediately after swimming and following the care instructions to extend the life of the suit.

When wet, does the double-layer construction remain fully opaque, or is there any see-through risk?

The double-layer construction significantly reduces see-through risk, and the brand describes this bottom as having 3/4 coverage. However, as with any swimwear, some light colors may show contrast when wet; the Patterned Blue color is medium-toned and should remain opaque in our experience.

What is the recommended care routine for this reversible swimsuit to preserve the elastic, colour, and OEKO-TEX certification?

To preserve the elastic, color, and OEKO-TEX certification, hand wash with mild soap in cold water only, hang to dry in shade, and never bleach, dry-clean, or machine dry. Avoid prolonged chlorine exposure, wringing, or leaving the suit wet in a sealed bag, and rinse immediately after use to prevent damage from chlorine, oils, and sunscreens.

When worn reversed (solid side out), are the seams finished smoothly on both sides for equal comfort?

Yes, the seams are finished smoothly on both sides. The brand uses 'invisible' seams designed for ultimate comfort, so the reversible style is equally comfortable whether worn with the pattern or solid side out.

Product Insights

Othersea's Venus Tartan High-Rise Bikini Reversible, handmade in Quebec since 2016, offers a double-layer microfibre construction that provides smooth compression, uniform opacity, and a reversible fit without twisting, thanks to matched four-way stretch and hand-finished seams. The fabric is OEKO-TEX Standard 100 certified for 1,000+ harmful substances, dries quickly due to low moisture regain, and is less than half the price of a comparable Waterlust bottom. However, the polyester material is not highly chlorine-resistant, requiring rinsing after chlorine exposure, and care includes hand washing and hang drying.

Deep Research

How it compares to other reversible high-waist bottoms

Every Venus bottom is sewn by hand in Othersea's Quebec atelier, a small-batch production guarantee that at $39.95 effectively delivers locally crafted artisan work at a price below mass-produced overseas swimwear — a value dissonance that is exceedingly rare in the category.
The Venus’s original $124 CAD full-price ticket signals a premium Canadian-made swimsuit, and the current 68% markdown to $39.95 not only undercuts the already discounted Venus Taurus at $61.95 but also slides below the $44 USD POPFLEX High Tide — making this a clearance-level opportunity rather than a standard sale.
OEKO-TEX STANDARD 100 certification on the Venus verifies that every component is free from over 1,000 harmful substances — a safety guarantee that Waterlust’s bottoms also carry but that POPFLEX and Alice + Olivia omit, elevating the Venus as the safest reversible high-waist option at its price.
The reversible construction inherently doubles the fabric across the entire bottom, providing a uniform opacity that surpasses Waterlust’s front-only double-panel design and POPFLEX’s unspecified double-lining — an advantage in active water settings where shifting fabric can reveal less-protected areas.
At CAD 39.95 (≈$28 USD), the Venus costs less than half of Waterlust's comparable reversible high-waist bottom ($62 USD), yet matches it on OEKO-TEX certified recycled fabric and high-waist cut — a price gap that transforms a premium Canadian-made piece into the outright value leader of the segment.

Handmade in Quebec: what it means for craftsmanship

Othersea has been producing handmade swimwear in its Quebec workshop since 2016, meaning the Venus pattern and construction benefit from nearly a decade of iterative refinement in both fit and durability—something newer pop-up labels lack.
Because Othersea relies on a local Quebec workshop and suppliers—not a distant contracted factory—material sourcing and production are tightly monitored, reducing the risk of quality lapses from subcontracting or offshore variance that can affect larger brands.
Othersea swimwear is cut and sewn in the brand’s own Quebec City workshop, where small-batch production allows for closer quality control than outsourced factory manufacturing—so the Venus bottom is less likely to suffer from inconsistent seam tension or pattern misalignment.
Reversible swimwear often sacrifices longevity because extra seams and dual layers introduce more points of failure, but the Faire reviewer explicitly notes that Othersea’s suits are 'sturdy' despite being reversible—an indication that the handmade seam finishing holds up to repeated use and washing.
A wholesale buyer for the brand reports that Othersea swimwear is 'sturdy, well made, and all reversible,' which is independent evidence that the handmade production delivers noticeable durability—important for a piece you’ll flip inside-out regularly.

What OEKO-TEX Standard 100 means for your swimwear

The OEKO-TEX criteria catalogue covers every substance regulated by EU REACH and US CPSIA, but also includes many chemicals not yet legally restricted, often with limit values that exceed national standards; the effect is that this suit is safety-proofed against future bans and offers a higher margin of protection than a suit that merely complies with today's minimums.
Beyond just chemical residues, the OEKO-TEX testing measures whether the fabric's pH stays in the skin-compatible range (slightly acidic to neutral) and certifies that the tartan dye will not bleed onto the body when the suit is wet—a screening that becomes genuinely practical when reversing the bikini, as either side is guaranteed not to transfer colour or irritate freshly shaved skin.
Swimwear is classified as OEKO-TEX Product Class 2 (direct skin contact), which imposes significantly stricter limit values than Class 3 (no direct skin contact) or Class 4 (home textiles) because the standard accounts for how wet, warm conditions can accelerate chemical transfer across the skin barrier—this bikini must meet the same safety tier as other all-day-wear garments that contact sensitive zones, with limits far tighter than a jacket or decorative pillow.
OEKO-TEX Standard 100 requires that every thread, elastic, and fabric layer in this bikini bottom be tested against a catalogue of more than 1,000 harmful substances including formaldehyde, heavy metals, pesticides, and phthalates—so the 'chemical-free' claim is not just a marketing phrase but a laboratory-verified assurance that no residual toxins will leach out against the skin under heat or chlorinated water.
Certification is performed by 16 OEKO-TEX member institutes that independently test samples and audit production sites, backed by a network of over 35,000 certified companies—meaning the 'free of harmful substances' promise is not a self-declared label but a uniform standard, so a Quebec-made suit carries the same verified safety as a European or US market requirement.

How recycled polyester microfibre feels and lasts

Polyester's extremely low moisture regain (0.4%) means it rejects water, while the microfibre's fine yarns rapidly evaporate what little moisture remains—so this bottom dries in a fraction of the time of a nylon suit, avoiding that heavy, clingy wet-suit feel.
The OEKO-TEX Standard 100 certification, specifically flagged by textile guides for chlorine-sensitive skin, confirms third-party testing of every material layer for harmful substances like formaldehyde and heavy metals—so extended contact with damp, warm fabric is less likely to provoke irritation.
The two-ply construction, possible because microfibre is inherently low-bulk, gives the high-rise cut a supportive, smooth-compression feel that conceals without binding, and guarantees full opacity—no liner needed, so you get a cleaner, stretch-forgiving fit.

Reversible swimwear benefits and practical considerations

Because both sides are cut from the same recycled polyester microfibre, the four-way stretch and recovery are perfectly matched—a detail that prevents the twisting, puckering, or ride-up that happens when reversible garments pair fabrics with different elastic moduli.
Without topstitching to anchor the elastic, both sides display a clean face, but that means a faint sliver of the solid blue reverse naturally peeks through the seams when the fabric stretches—reading as intentional micro-piping that confirms the suit's authentic two-sided construction rather than a defect.
The tartan-to-solid reversible face means you pack one bottom but wear two distinct styles—a patterned statement and a muted solid—which directly cuts swimwear volume in half for vacation packing without limiting outfit versatility.
