    Great pregnancy staple
    I practically live in these leggings and have just ordered a second pair! I wear them for my yoga class, to work with dresses and at the weekend with long jumpers. I have had very sensitive skin during this pregnancy but the material of these leggings is so soft, it is really comfortable. I was a UK size 10 pre-pregnancy and I ordered size Small and it fits very well.

    Adore these leggings
    I bought my first pair in 2015 when pregnant with my daughter. I have bought approximately 6 pairs over the last 3 years and am now wearing them pregnant with my son. Best, leggings, ever. Comfortable, durable and not transparent!
    Review by Sally
    No. 1 must have in pregnancy & beyond
    These are the best leggings I've ever had. I've worn my last two pairs for a year so far and I'm just wishing Seraphine would bring back some of the other colours - pregnant or not, they are super comfortable, smart and cool, and they fit like a dream :D

    My number 1 leggings
    Best leggings I ever had, these bambo maternity leggings super soft and comfortable. I think I will definitely be wearing them even after having my baby as they will still be good. I just wish if Seraphine makes them in different colours.

    Brilliant leggings
    I absolutely love these, I bought 3 pairs while pregnant and am still wearing them a year after giving birth! Very soft, very comfy, and not at all see through.
    Review by Josie
    Most comfortable of them ALL!
    These are the most comfortable leggings I own so far. My little one was born in May and I still wear them! I was searching for the leggings in blue today but it seems that they have been discontinued... Seraphine, please make these leggings in more colours again! These have become my Number 1 leggings, irrespective of pregnancy!!! ;)
    Review by Ridhi
    please make more colors!
    These are comfortable, super soft, warm but also super breathable, and basically the best leggings I've ever tried! I have 39" hips and muscular thighs, the medium fit better than the small. I would love to buy them in gray and navy, if they were available!!!

    Bamboo leggings 6 stars!!
    These are the best leggings by a mile! Love love love! No seams and so soft, I'm ordering two more pairs they are so comfy!!
    Review by Julia
    Can't live without them!
    These are THE best maternity buy I have made. I now own 6 pairs in black, grey and blue! (Sadly the last 2 have been discontinued now I think) and I wear them every day. I actually bought them pre-pregnancy as they were so comfy and now i'm 21 weeks and honestly can't be in anything else. Even maternity jeans feel too tight, these are just perfect however with a dress over the top or a long top. They stay up well, give you a bit of support and generally just don't get in the way of your bump. I tried the over bump leggings but found these far too restrictive.

    Beautifully Soft
    I am absolutely thrilled with my Active Under-Bump Maternity Leggings. I am usually a size 10 on my bottom half pre-pregnancy and the size S/M fits me really well at 19 weeks. These leggings feel beautifully soft and very good quality, plus there is plenty of stretch in them too. There are no nasty seams to dig in on these leggings which I am vet pleased about and I like that it sits under my bump. I would say that these are more like thick tights in terms of coverage, if you bend over in them you can see your knickers which would be a problem if you wore them with shorter tops. I have purchased these in navy and black and I am confident that they will be wardrobe staples for me with dresses and long tops. Thank you Ruth Crilly, Author at The Uphill blog and a Model Recommends, I read about these beautiful leggings on your blog.

    Absolutely brilliant
    The best thing I brought during my pregnancy. They were long but it didn't really matter. They were not at all see through - a real issue with leggings from the high street. Now I'm not pregnant I have looked every where for something similar but can't find them - please make post pregnancy ones!

    Great and comfortable leggings - nice tight fit, they are very supportive and don?t fall down like most other leggings - and no baggy knees! Lovely quality, nice fabric and good support, they are also lovely and warm
