Are your Carry Me Belly Bands suitable for post partum as well as pregnancy?
Our Carry Me Belly Bands have been medically endorsed for use during pregnancy.
The maternity waistbands and high waistbands on our Ultra & Revolution range offer amazing comfort and light compression around the mid section and are highly recommend for post-partum support.
These waistbands have been endorsed for post-partum use by a Women’s Health Physiotherapist.
The Carry Me Belly Band can be used postpartum, but we recommend it’s use
for light support only. We do not endorse this band as a waist trainer/reducer.
I have been sent the wrong size Birthing Ball. What can I do?
We have a robust inventory control procedure in place to ensure the correct size ball gets dispatched every time. However, the ball can often seem too small on it’s first inflation so here are a few tips to help get it to the correct height:
Give these tips a go and if youre still having no luck, please feel free to contact us with your order details and a photo of your ball and we will do our best to help.
Is your sizing the same for all activewear and swimwear?
We try to keep our sizing as accurate as possible, although some products are designed to fit a little differently to the next. We recommend reviewing the sizing guide as well as individual product descriptions for any sizing recommendations. If you have any sizing questions, please feel free to contact us as we are always here and happy to help.
What activewear do you recommend for pregnancy?
Pregnancy is such a special time in your life and we want to help make your journey easier with our range of designs to support you from the very beginning.
We recommend products that will
support your bump, offer light compression, fit well and help you feel
good, look stylish and radiate confidence!
Check out our pregnancy collection here.
When is the best time to start wearing maternity clothing?
This comes down to personal preference but we will say this: maternity wear is a game changer!
As you grow throughout pregnancy, your existing clothes may start to feel
too tight or become uncomfortable to wear. This is usually the best
time to invest in clothing designed for maternity. Many of our pieces are designed to be worn throughout pregnancy and beyond so you can start
choosing pieces that will carry you through your post-partum journey
during your pregnancy too.
Clothing designed specifically
for use throughout your maternity journey can offer support and comfort
without compromising style and practicality. We have often received
feedback from our lovely Mamas saying they wish they had tried maternity
wear earlier in their pregnancy or with previous pregnancies – it definitely helps make life more comfortable, manageable and convenient and let’s face it, who doesnt love a little extra help with #mumlife!
What sort of bra do you recommend for pregnancy?
All of our bras are designed and suitable for pregnancy. They include features such as adjustable straps, extra wide back hook/latches and all-elasticated under bust bands to ensure optimum
comfort, support and room to grow.
We understand how difficult it can be to know (and keep up with!) your bust size as sizing often fluctuates throughout pregnancy and once your babies arrive. We have a detailed sizing guide
available so you can find your perfect fit. We also offer a range of bras that can support you in any level of exercise intensity on your journey.
What fabrics are used in your clothing?
We aim to use a range of sustainable fabrics such as cotton and recycled polyester where we can.
The fabric composition for each product is detailed in their product description.
