stage guide
Ribcage expanding, bloated, between sizes, bump growing, or a favourite bra that's gone a little snug? Hotmilk bra extenders add up to 5cm to your band, so the bras you already own keep fitting through pregnancy, postpartum, nursing and every in-between day. Each extender adds 3 extra rows of adjustment, and the 3 pack comes in black, white and frappe to match your lingerie drawer.
Key Benefits
-
Up to 5cm of extra room: Each extender adds up to 5cm to your band for all-day comfort, without buying a new bra.
-
For every stage: Pregnancy, postpartum, nursing, bloating, weight changes or sitting between sizes.
-
3 rows of hooks: Adjust the fit in small steps as your body changes.
-
Detachable and reusable: Clip on when you need it, take it off when you don't.
-
Easy to attach: Hooks onto the back closure of your Hotmilk bra in seconds.
-
3 colours in one pack: One black, one white and one frappe extender to match your bras.
-
Fabric: Polyamide, elastane and metal hooks.
-
Care: Gentle hand wash, line dry.
For hygiene reasons, bra extenders are final sale and cannot be returned or exchanged.
Who is this for?
Any woman whose bra fits in the cups but feels tight around the back. That includes pregnant mamas with an expanding ribcage, new mamas whose body is still changing, and anyone who bloats, fluctuates in size or sits between band sizes. An extender is the simplest fix.

Super handy - has extended the use of my bras (even non-maternity ones) past 34 weeks and my ever expanding back!
Super handy during pregnancy! Great quality!
Thank you for your review Mai! xx
Excellent product to make bras fit throughout pregnancy.
And a great thing to have on those days when everything is just feeling a bit tight x
I love these extenders - I’ve never used any before but they’re just perfect, I don’t even notice that they’re there and they allow for a more comfortable bra fit as my ribs continue to fluctuate throughout my pregnancy.
A great way to be comfortable in those last few weeks before delivery and as your body recovers x
These were a revelation to me. It means I've had so much more wear out of my maternity bras I bought earlier on in pregnancy. Definitely recommend.
What a great invention - managed to use on my old bras for my last weeks of pregnancy before I start wearing the new nursing bras I bought at the same time! Would recommend :)
Fair price and good for different brands sizes and types
Works well stays put.
I really like how these allow me to extend my band size gradually as I've got a short torso and that area expands quite quickly. With 30w+ my cup size hasn't changed from pre-pregnancy size yet so I am still able to wear my regular bras with the extender, which works perfectly fine too when your bra has only 2 hooks as well.
Easy fantastic service
Very handy little extenders
