Secret Weapons

Secret Weapons is an Australian fashion-solutions brand created for the awkward gaps between underwear and clothing: the backless dress that will not take a normal bra, the bra band that needs a little extra room, the neckline that shifts, or the fitted outfit that needs a smoother base.

The brand has been developing these wardrobe fixes for more than 20 years. Its range spans stick-on bras, boob tape, inserts, bra extenders, clear straps, fashion tape, seamless underwear and even shoe accessories. Most pieces are small and discreet, but choosing the right one can completely change how an outfit fits.

Secret Weapons works best when you start with the clothing rather than the underwear. A deep back may call for a low-back converter; a plunge neckline may suit tape or a stick-on bra; a slightly tight new bra can often be made wearable with the correct hook-count extender.

These are not interchangeable products. Boob tape is used to lift and position the breast directly on the body, fashion tape is used to hold fabric in place, and inserts sit inside a bra or swimwear cup to add shape. Choosing the correct tool is more important than choosing the most dramatic one.
