I found working out the size to be the hardest as I have never bought clothes online before. Belly thanks to Menopause so wanted to make sure they fitted comfortably and not too tight around it. Mine are too big, comfortable in the belly and pretty sure I could go a size down in the waist and way too big in the legs. However I kept them to wear around the house because easy to pull up and down when going to the loo! Plus the high waist is good. I am hoping the next size down will be tighter in the legs but I don’t think so. If you want to accommodate a big belly you get bigger legs which I don’t have. It would be great if they made bike pants..the bike shorts are a little too short for an oldie like me! In Qld the 3/4 are too hot in Summer.
I got these pants for my first 10k run on the weekend and they didn't fall and ride up at all. So comfortable and loved wearing these. Love how high wasted there are too.
I love these leggings! As a plus size person it's hard to shop online wondering if clothes will fit you right but these are a perfect fit for me and don't roll down! Love all the little details on them and they are very comfortable! So glad I stumbled upon Mama Movement on Insta and looking forward to shopping again with them :)
I love them! They hold everything in place perfectly and they feel amazing to touch very smooth. I’m going to buy the 3/4 ones too!
Love the high comfortable waist. The bike pants run very true to size and feel great although the inner leg seems more like 10” than 8” and I’d prefer the latter (hence will now try the shorties).For those with larger hip than other parts you may find the bottom of the leg a bit loose as I did.

This is the second Mama Movement jacket I've bought for my daughter and she loves it. Stylish and functional
I love it. It came in perfect time for me to wear while doing afternoon chores (and saving the semi-tame cat from deep water.
I used the measurements to figure out what size to get but decided to size up and am glad I did. I am an 18-20 in regular clothing shops, and wear 3xl in the skorts from here but went for the 4xl in the longline raincoat. I find it fits comfortably and allows movement- and I live that when I need to crouch etc I can unzip from the bottom to give extra room.
My hips are my widest part and I was at the in between of sizing for them but am glad I went with the 4xl because I do have sensory issues. Amusingly enough- my autistic teen did steal it to run around and jump in puddles- and can confirm, even if massively oversized (he is an XS mens clothing fit and tall) it is still extremely comfortable to wear.
Fun print, amazing quality and love the length
LOVE THE COLOUR as well as the material, the feeling is like a warm hospital blanket when you put it on. It’s very lightweight as well which makes is early to wear daily.
Love my Electric Leopard leggings! They’re comfy and fun to wear. Always get lots of positive comments. Thank you Mama Movement!
I love the sunny weather but now I have received this fabulous jacket I just want it to rain!! Perfect fits well lightweight and beautiful pattern. I love it was designed by someone who has the surname “Rainbow”
