Available D–J cup, bands 32–38 (F–J) and 40–42 (F–H)
Fuller HH/J cup? Consider sizing up a band for the best fit
6-hook closure extends +9cm — the most generous band extension in our range
Flawless uses structural engineering rather than wire to create lift:
- Three-piece cup construction shapes and supports without compression
- Double-layer side shaping panels create structure from the sides
- Sheer plunge neckline adds the visual depth of a plunge while the cup provides full coverage underneath
This is specifically designed for F–J cup — not a scaled-up smaller style.
Flawless fits true to size and has a stretch top cup so it can adapt to a cup size bigger too — choose your regular size. No padding — designed for a natural, comfortably supported bust shape.

Yes — Flawless is designed for pregnancy through to weaning. The +9cm band extension means it adjusts as your body changes. Many customers find a plunge style more comfortable in late pregnancy as it avoids pressure on the upper chest.
