Quick Answer
For the Medusa High Waisted Bikini, start with your usual Thistle and Spire panty size, then use the slidable side adjusters to fine-tune the fit for a cheeky but secure silhouette.
Why Fit Matters for This Style
The Medusa High Waisted Bikini offers more coverage than a traditional thong, but its cheeky cut still leaves part of the backside exposed. Getting the size right ensures the embroidery sits where it should and the waistband stays put without digging in.
Because this is a final sale item, choosing the correct size upfront is especially important. There are no refunds or exchanges, so taking a few minutes to measure and read the fit notes can save you from disappointment.
What Makes the Medusa Different
Unlike some high-waisted briefs that rely on a fixed elastic band, the Medusa uses slidable side adjusters. This lets you tighten or loosen each side independently, which is helpful if your waist and hip measurements fall into different sizes.
The fabric is a smooth, silky stretch material that hugs the body without compression. If you are between sizes, the adjustability usually allows you to go with the smaller size and loosen the sides for a custom fit.
How to Find Your Medusa High Waisted Bikini Size
- Measure Your Waist and Hips: Use a soft measuring tape. For waist, measure at the narrowest point (usually just above the belly button). For hips, measure at the widest part around the buttocks. Compare both measurements to the Thistle and Spire size chart. If your waist and hip measurements fall into different sizes, choose the larger size and rely on the slidable adjusters to tighten the waist.
- Check the Size Chart for Your Usual Panty Size: Thistle and Spire panties generally fit true to size within the brand. If you already own a high-waisted brief or bikini from them, start with that same size. The Medusa cut is similar to other cheeky high-waisted styles. Do not automatically size up for more coverage — the slidable sides let you loosen the fit if needed.
- Consider the Fabric Stretch and Adjusters: The silky stretch fabric moves with your body, and the side adjusters allow up to about an inch of adjustment per side. If you are between sizes, try the smaller size first and loosen the adjusters. If the waistband still feels tight, go up a size. Common mistake: pulling the adjusters too tight can create a muffin-top effect. Keep them snug but not compressed.
- Check the Back Coverage and Rise: The Medusa is a cheeky cut — it covers more than a thong but less than a full brief. The high waist should sit at your natural waist or just below. If the waistband rolls down, the size may be too large or the adjusters too loose. If the waistband rolls or the back coverage feels too revealing, tighten the adjusters slightly rather than sizing down.
- Try It On and Adjust Before Wearing: Because this is a final sale item, try the bikini on over clean underwear or hosiery first to check the fit. Adjust the slidable sides evenly on both hips until the waistband lies flat and the embroidery is centered. Walk around and sit to confirm comfort. If the fit feels off after adjusting, do not force it — the final sale policy means you cannot return it, so be certain before removing tags.
