PRODUCT DESCRIPTION

The Third Form Hidden Gem Tank Maxi Dress in Black is a black tank maxi dress with a quiet twist. Cut from a soft bamboo stretch blend, it skims the body in a slim, considered fit, then catches the eye with five custom-cut organic stones set into a keyhole cutout at the front. It's the kind of maxi dress that reads simple from across the room and rewards a closer look.

The lightweight, breathable fabric means it moves easily from a dinner reservation to a night out without ever feeling fussy. Style it with delicate gold jewellery to let the stone detail shine, or add a blazer for cooler evenings. Find more statement silhouettes in our Maxi Dresses edit.

THE DESIGNER

THIRD FORM

Third Form is a Sydney label started in 2014 by Merryn Kelly, built on a simple idea: sharp minimalism with just enough edge to keep it interesting. Expect clean lines, considered cuts and a palette that leans neutral without ever feeling flat.

The dresses are where this shows up most, from fitted midi styles to more fluid, occasion ready pieces, alongside tailored separates and jeans built for the same easy versatility. It's a wardrobe that works as hard at the office as it does after hours.

At BELLA n' BEAR, we stock a considered edit of Third Form dresses, tops and jeans across the seasons. For something with a bit more colour or print alongside it, our Black Dresses edit sits well in the mix. Browse the current range below.
