If you ask any user of period underwear to name their biggest pain point, the answer is almost universally the same: "Changing them in a public restroom."
The logistical nightmare of removing shoes and trousers in a cramped cubicle is a significant barrier that prevents many consumers from adopting period panties as a full-time solution.
For innovative brands (like those targeting the active or accessibility markets), the next growth frontier is Detachable Period Underwear (or "Quick-Change" panties). However, designing a side-opening product that doesn't chafe, leak, or unhook unexpectedly requires serious engineering.
Here is how Ljvogues solves these technical challenges to help you build a "24/7" solution.
Standard period panties are excellent for home use or overnight protection. However, for a 9-to-5 workday, a long-haul flight, or a hiking trip, they can be inconvenient.
The Market Gap: A side-opening design allows the user to change the underwear just like a diaper or a bikini bottom—without removing pants or shoes.
The Value Proposition: This simple innovation transforms period underwear from a "home-only" niche product into a versatile "All-Day Solution," significantly increasing the potential units per customer.
The closing mechanism makes or breaks the product. We have prototyped and stress-tested dozens of variations. Here is our verdict on the two best options:
Pros: Extremely secure (won't pop open when sitting), features a very flat profile (low visibility under tight clothing), and offers adjustable width (similar to a bra strap).
Cons: Can be slightly fiddly to close blindly; metal hooks must be nylon-coated to prevent skin irritation.
Best For: Sleek, high-fashion styles, office wear, or activewear where security and a smooth silhouette are the top priorities.
Pros: The easiest to use (quick click), tactile feedback, and high durability.
Cons: Can create a visible "bump" on the hip; if placed poorly, they can dig into the skin when the user sleeps on their side.
Best For: Heavy-flow/overnight styles, teen collections, or accessibility-focused designs (for users with limited mobility).
Beyond side-opening designs, we are pioneering the "Floating Gusset" (Removable Insert) system.
The Concept: The underwear body stays on, but the absorbent core is held in place by silicone grip strips or mini-snaps. The user swaps only the pad-like insert.
The Engineering: We create a "pocket" or "rail" system in the crotch that locks the insert in place. This prevents the "shifting" common with disposable pads, offering the stability of underwear with the convenience of a pad.
The biggest risk with detachable panties is leakage at the connection point (the side seam). If fluid migrates to the edge, it can wick onto the user's clothing.
Barrier Extension Strategy: We extend the waterproof TPU layer past the absorbent core, wrapping it slightly around the hip connection area. This ensures that even if fluid migrates sideways, it hits a "waterproof wall" before reaching the hook or snap.
Hydrophobic Thread: We utilize specialized non-wicking thread at the side seams. This prevents fluid from traveling through needle holes via capillary action to the outer clothing—a detail many manufacturers overlook.
Sewing a hook-and-eye tape into a stretchy waistband requires precise tension control. If the tension is off, the waistband will ripple, or the hooks will tear out after just a few wash cycles.
At Ljvogues, we use specialized attachment machinery (similar to high-end lingerie production) to ensure the fasteners are "bomb-proof" secure while remaining soft against the skin.
