    Light & nice material

    They are nice but they hung so strange on me that I looked too weird and had to send them back. I own a variety of L&Y clothes so. It sure why these ones look so odd but I’d love to see more light eco trousers in other fits this summer please. They are ideal for packing.

    Poor quality

    I love these trousers, they’re so comfy and flattering. I adore the Lucy and Yak brand and that they cater for my height and size. Unfortunately my trousers are unwearable as the seam on the right leg has not been sewn properly, the thigh is now tearing apart and holes have appeared. I have had these trousers less than 6 months and the cost per wear is high due to the quality being low, something I wouldn’t expect from the brand. Very disappointed and sad that these trousers have let me down because they are my favourites.

    Hey Ellie,

    Thanks for taking the time to review your Billie's. We're so sorry to hear about your experience with these - this isn't the quality we would expect from our garments and it sounds like you may have received a faulty pair.

    Our Customer Happiness team have just sent you an email to explore your options and make things right!

    Awesome trousers

    A fab addition to my wardrobe. Super comfy trousers, exactly what I was after!

    Converted- perfect trousers for this wheelchair user

    I started off very unsure of these trousers. I did not know if they would have a deep enough seat (or stay up on a seated wearer), I was also worried that they would be too tight in the hip and thighs (size M alexas are too small and L come up giant on me- requiring a belt).

    So I had prepared to gift them on…
    However these trousers are PERFECT, I am excited to see if any prints will be made for them later in the year. So comfortable, they also layer well, so I can wear them over compression gear and/or thermal leggings. Thank you for letting me feel great about my appearance on flare days!!

    I will definitely be trying out the corduroy versions soon

    Come up smaller than Alexa's

    These came up a tad bit smaller than Alexa's for me and are not as high waisted. The material felt a lot like that of school trousers which I wasn't a fan of sadly 😔
