Customization Guide

• 💡 Since 2017, styles with a 4th code digit of 1, 3, 5, or 7 often offer optional back piece changes.
  For example, H1 can be switched to T1 (no extra charge), or to Y1 (extra charge applies).
  These changes are selectable during ordering and are not part of full custom tailoring.
• New designs (from 2017) are not compatible with old designs (2009–2016), so back cuts like B1, H1, or Y1 cannot be applied to earlier versions.
• We offer a variety of back styles, ranging from sexy to playful. Each back type is available in four waist heights. For Y-style thongs, the heights are: Y0 — low rise, Y1 — super-low rise, Y2 — ultra-low rise, Y3 — extreme-low rise (minimal). Y1 is our default height.

• iSwim prioritizes both comfort and sexiness. Pouch volume remains fairly consistent across sizes; only waist and vertical height vary. (For some styles, the front height of size L is the same as size M from 2017 onwards.)
• If you’ve worn the same style before or feel that the pouch is too tight (especially for Western body types), feel free to note 'Pouch +1cm *2' in the order comments. We’ll increase the depth by 1cm on each side. Some styles allow up to +2cm *2.

• Most styles from 2017 onward are designed with specific fabrics and colors. To request a change, please choose 'Other Material/Color' (if available) and indicate the material and color code in the order notes. Requests without this selection cannot be processed.
• For 8mm strap styles, fabric options are limited. Please refer to styles with a 4th code digit of 3 👉 u3, or contact us for suggestions.
• If you'd like to convert underwear styles to swimwear fabric, the item will still be made to underwear sizing. A base handling fee of NT$350 (or 50% of the item price) will apply. Other changes (e.g., back cut, ruching, color mix) will incur additional charges.

💡 All 8mm strap underwear cannot be made using swimwear fabric.

💡 All swimwear styles cannot be converted to underwear due to structural and waistband design differences.

• Since April 2022, logo tag placements have been adjusted for better comfort and fit. Final positions may vary slightly by design. Thanks to all the fans for your feedback!
• Since October 2018, we no longer accept requests to remove the logo tag or care label. If noted in the order, only the care label will be removed by default.
