Start with the size range, not the color
The High-Waisted Retro Bikini in Thistle is offered in one size option: Fits 16-24. That single range is the first thing to check before you think about styling. If you usually fall inside that band, the retro cut is designed to give you full coverage with a smooth, no-show finish. If you are outside it, this particular pair is not the right starting point, no matter how much you like the thistle shade.
This is also a final-sale item, so the usual back-and-forth of trying two sizes is not available. Treat the size range as a firm filter and read the fit notes below as a way to decide whether the cut suits how you want underwear to sit.

High-Waisted Retro Bikini - Thistle (Final Sale) - High-Waisted Retro Bikini - Thistle (Final Sale): High-waisted bikini with full coverage and a smooth, no-show finish. Explains why the cut is aimed at wearing under clothes without visible lines.

- High-Waisted Retro Bikini - Thistle (Final Sale): Final Sale item, catalog price USD 16.28 (comparison price USD 22.00). Final-sale status means you cannot rely on returns for a size mismatch, so the size range matters more than the discount.
How to check the fit before you commit
- Confirm you are inside the Fits 16-24 range: The product lists only this size option. If you are at the edge of the range, decide based on how you like high-waisted waistbands to feel rather than guessing at a second size.
- Decide whether you want full coverage: The retro bikini is described as offering full coverage. That is a different feel from a thong or a lower-cut brief, so choose it when coverage is the priority.
- Match it to the clothes you wear most: The no-show finish is the feature to lean on. If your daily outfits include leggings, close-fitting skirts, or light trousers, this is the scenario the product is described for.
- Accept the final-sale tradeoff: At USD 16.28 against a USD 22.00 comparison price, the saving is real, but final sale means the size decision is yours to get right up front.
What thistle does for styling
Thistle is a muted, dusty purple tone rather than a bright statement color. That makes it an easy pair to wear under light or neutral clothing without the color shouting through, and it also looks intentional if the waistband shows above a low-rise jean or under a slightly sheer layer.
The supplied product information does not include fabric composition, exact rise measurements, or care instructions. Those details are not confirmed here, so avoid assuming a specific fiber content or washing method. What is confirmed is the coverage, the no-show finish, and the size range. Style around those facts and check the garment label when it arrives for care guidance.
Ways to wear the Thistle retro bikini under clothes
- Under leggings: This is the use case named directly in the product description. The high waist and no-show finish are meant to keep the line smooth through the seat and hip.
- Under skirts and dresses: Full coverage makes this a practical choice when you want to avoid a visible panty line through lighter fabrics. Pair it with skirts you already wear rather than buying new ones.
- As a visible waistband: If you like the high-waisted look, let the thistle band show above low-rise trousers or under a cropped top. The color is quiet enough to read as a deliberate layer.
- For everyday rotation: The product is described as a pair you will reach for day after day. Treat it as a daily basic rather than occasion underwear, and build your laundry routine around that.
Where this pair stops being the right choice
If you are outside the Fits 16-24 range, this specific listing will not work for you. If you prefer a minimal-coverage cut, a high-waisted bikini with full coverage will feel like more fabric than you want. And if you need to try multiple sizes before deciding, final sale removes that option.
The honest summary: the Thistle retro bikini is a good fit if you are in the listed size range, want full coverage, and care about a smooth line under leggings and skirts. The color is a bonus, not the deciding factor.
