I love what I have purchased so far. About to buy another pair.
One of my fave shorts and so comfy! Perfect for summer workouts and fun in the sun.
These shorts are super cute and also super comfy. The Lucy Leopard range has great colours to wear casually as well as for active wear so I’ve been wearing my shorts everywhere! The shorts are very flattering and flatten your tum. Very comfy to exercise in.
These black shorty bike shorts are the most comfortable undershorts. I wear a lot of dresses and am loving the shorter length, note I am short anyway so this length on me is probably normal on others ;-). They don’t ride up. Most definitely recommend to really read all the notes regarding sizing, give yourself the best possible chance to get the right fit straight up… loser fit size up, firmer fit size down. Never ever thought I would order a larger size but oh my goodness best decision ever.
My first pair of MM bike shorts (have leggings and running shorts!) - could not resist this pattern.
Comfortable, well fitting, and dopamine dressing at it's best.

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”
