Fast Shipping Guarantee

We know you’re excited to try them, so we pack your order fast. Most orders ship within 1–2 business days, and every order ships within 2 business days, guaranteed.

How we count. The day you order is day 0. Business days are Monday to Friday, excluding U.S. federal holidays. Order on Monday, it ships by Wednesday. Order on Saturday or Sunday, it ships by Tuesday. “Ships” means your package is handed to the carrier and your tracking number is emailed to you.

If we’re ever late, it’s on us.

  • Ships on business day 3 or 4: 50% of your order is free. We refund half of your item total to your original payment method.
  • Ships on business day 5 or later: your order is free. We refund your full item total.

It’s automatic. There’s nothing to claim, and we’ll email you when your refund is on its way. “Order” means the items you paid for; shipping, Shipping Protection and taxes aren’t included. One guarantee refund per order.

What it covers. The guarantee covers when we ship. Once your package is with the carrier, delivery time depends on them. Your estimated delivery date is shown at checkout. It applies to orders placed on spicywear.com, in the U.S. and internationally.

What ships on its own timeline: pre-order or “ships by” items (the date is shown on the product page), orders you’ve asked us to hold or change, orders waiting on information from you (like an address check), orders held for a payment or security review, orders placed through TikTok Shop or other marketplaces, and carrier or weather disruptions outside our control.

Busy times. During launches, Black Friday or other busy periods, we may post a different ship time on the site before you order. Your order follows the ship time shown when you placed it.

If your order is going to be late, we’ll email you right away. You can cancel for a full refund, or keep your order, and the guarantee still applies.

  • ★★★★★S.R.

    “…I can stay in them all day and be working on my feet doing squats and moving a whole lot and never feel a thing.”

  • ★★★★★P.

    “…the wide gusset is so comfortable and the back as well! Way more comfortable than my typical thongs. I never think about the y-string throughout the day, it's that comfortable.”

Say goodbye to uncomfortable G-strings and hello to the Y-String®: string underwear redesigned for comfort, coverage, and confidence.

No Slips, Just Comfort — A wider front gusset gives you a smooth, fully-covered fit with no wedgies and nothing riding up or shifting all day.

Body-Size Softness — Petite or plus-size, the Y-String provides all-day softness you barely feel.

Breathable — A 100% cotton gusset keeps you fresh and comfortable, even during the longest wear.

Minimal Lines — A 1 cm wide string keeps lines minimal, so discreet you'll forget you're wearing it.

Loved by Customers — One of our highest-rated styles. Once you try it, you'll never look back.

Made with 100% cotton gusset, 95% cotton, 5% spandex.

Get the Y-strings!

I have never been a thong girl before these. Trust me, I tried. These Y-strings solved every problem I had with a normal thong or G-string. The gusset is SO spacious and I don’t feel like I’m being flossed to death in the back. And let’s be real, the red ones are so sexyyyy.. Now I always reach for these first.

Best underwear ever!

I love these underwear. They are literally the only thing I wear now. Threw out all my expensive Victoria's secret and have exclusively worn spicy wear for over a year. My only complaint is not enough colors and patterns! Give a girl some variety!!!

Different strokes

So for disclosure, I'm a pre-op trans woman so my underwear choices can be fairly limited when trying to find something that's both effective and sexy but, a friend turned me into Spicywear and I absolutely love these Y-strings. I have no slippage, no panty lines and I feel sexy and affirmed all day. Thanks for making such a great product ✨

Sizing is off, please size up due to product runs very small. Unfortunately limited customer support.

My butt don’t eat em!

I have never been able to wear anything but granny panties because every thong/g-string gets DEVOURED by my butt. These were AMAZING. It does take a few wears to get completely used to the feeling, but they are very comfy!
