本款式採特定材質及顏色,如需更換材質 (或顏色),請您務必選取 其他材質/顏色 (如有提供),並在訂單結算時備註「材質-顏色」代碼於 [訂單備註] 欄內,如未提供「其他材質/顏色」選項者,請勿備註換料。

💡 8mm細帶內褲款式可使用面料有限,可參考 貨號 u30 開頭的細帶內褲(例如: 17u30** ... 22u30**)所使用的面料,或先向客服詢問。

💡 內褲款式僅可使用內褲專用面料,如改製成泳褲則尺碼將會以內褲為準,需酌加基本工本費350元起(色線配色、變更後片或拉縐加工等等需另酌加其他費用),比基尼泳褲一律使用iSwim Fashion所訂製的國際A+等級耐熱高回縮率橡膠帶(非常適合日曬使用)。8mm細帶內褲款式一律不提供使用泳褲面料(因為版型並無法直接用於泳褲)。

iSwim的設計概念以細邊及細帶性感低腰但更舒適為主,內褲/泳褲的前袋容量在不同尺寸是幾乎相同的,僅有腰圍和高度會不同(部份特定款式的前片高度並不會增加,自2017年起L碼的內褲前片高度將會和M碼相同),因為並不是臀部比較大、性器官就應該比較大!如果您曾經穿過同款式或感覺容量可能不夠(尤其是西方人),請在結帳頁面備註「囊袋 + 1cm * 2」於訂單的備註欄,我們會為您將囊袋的深度增加1cm(整體容量也會跟著稍微加大)。

💡 Underwear styles uses underwear fabrics normally. If you wanna change to a swim bikini, will need to extra cost from 350 TWD (Color deco lines, change style or wrinkle processing, etc. are subject to additional charges), and size will be based on underwear. The swimming bikinis will use the international A+ grade heat-resistant high-retraction rubber bands that customized by iSwim Fashion (very suitable for sun tanning). 8mm string underwear styles are not available to uses swimwear fabrics (because the cutting is not suitable for swimming bikini).

The design concept of iSwim is based on sexy low rise but more comfortable. the pouch volume of underwear/swimwear is almost the same in different sizes, only the waist and height will be different (The height of the front, some special designs will not increase. And the front height of the L size underwear is the same as the M size since 2017), because it is not a big buttocks it must have a bigger penis! If you have worn it or feel that the volume may not be enough (especially westerners), please indicate "pouch + 1cm * 2" in the [Order Remarks] field of order during checkout, and we will increase the depth of the pouch by 1 cm (The overall capacity will also be slightly expanded).

① "21s3013-A1" is a swimsuit fabric with a side width of "Sides 8mm ± 1mm" of 8mm, but could you make it with a swimwear fabric of 19u4015, 20u3018, 20u3022, 19u3021 with a side width of 8mm? (It is OK even if it is slightly larger than 8 mm.)
(2) Waist Size: M, if I'm slender, it will stretch when it gets wet, so could you make it with "Size: S"?
③ Rear piece: Can I ask for a full back?

C.S.2022-02-23 20:46:51

1. Please select [other fabric/color] first, for use underwear cutting to make to swimwear it will next extra 350TWD at least depending on the designs.
2. To use underwear cutting make to swimwear, the size will still base on underwear, if need smaller waist, please remark [waist-1cm*2], it will almost same as size S.
3. Our F1 is full back cutting, but it only a little wider than 3/4 back, not a really full back like the Arena/Speedo, hope you can understand.
