- Wire-free styles that lose all shape and lift above a G cup
- Needing a bra that adjusts as your body changes through postpartum
- Wanting sustainable fabrics without the stiff, clinical fee
- Plunge neckline with full wirefree support up to a J cup — because fuller busts deserve styling options too
- Wirefree Full Cup Support Three-piece cups with shaping panels deliver genuine — sculpted silhouette, zero compression
- Adaptable Fit 6-hook closure extends +9cm — the widest band extension in our range, built for the biggest body changes
- Certified recycled nylon, OEKO-TEX certified sustainable inside and out

Common Questions about Flawless Large Cup Bra
Everything you need to know about wirefree plunge support up to a J cup and sizing for fuller busts
Flawless fits true to size — choose your regular size
Available D–J cup, bands 10–16 (F–J) and 18–20 (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.
6-hook closure extends +8cm for postpartum adjustment

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.

our story
Born from a founder who refused to settle
Twenty years ago, Lisa Ebbing refused to wear nursing bras that made her feel invisible, just because she was becoming a mother. That refusal sparked a revolution. Today, Hotmilk has sold over 2.5 million maternity and nursing bras and briefs worldwide.
