Why we built Obsession
- Larger E–J busts with no T-shirt bra that gives a smooth finish under clothes
- Returning to work with nothing that holds its shape all day at E cup and above
- Underwire that digs into a fuller bust before lunchtime
- Standard bras scaled up — not actually built for larger cups
- Engineered T-Shirt for larger busts A T-shirt bra specifically built for E–J cup
- Spacer foam cups smooth and contour under anything you wear, all day, without losing shape
- Flexiwire Adaptability lifts and supports a fuller bust, moving with your changing shape without digging
- Wider band and straps Wider 4-row closure and wider 18–22mm straps on larger sizes: the structural details that make the real difference at E+ cup

Obsession 2.0 is engineered specifically for E–J cups — not a scaled-up version of a smaller style. Key design differences at E+ cup:
- Spacer foam cup depth matched to fuller bust proportions
- 4-row hook closure (wider than standard 3-row) for added band support
- Wider straps: 18mm standard, 22mm on the largest sizes (10HH/12H/14GG+)
- Double-layered band for extra smoothing
- Improved A-frame for larger cup access
Yes — Flexiwire moves with your bust, rigid underwire doesn't. The Australian Breastfeeding Association notes flexible-wire maternity bras are "less likely to cause problems." The A-frame clip releases fully during feeds, removing any pressure on breast tissue.
We offer 30-day returns on unworn bras with tags attached. We also have Refunds or store credit available.

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.
