Size M Colour Sorbet/Seashell
I love these leggings! I was a bit nervous about the colour as I'm not normally very outgoing when it comes to colour choices but these make me feel so confident. The pink is b.r.i.g.h.t. but not in an offensive way. They fit like a glove and I can (and have) comfortably worked out then eaten a takeaway in them - no bother! 10/10 would buy again.

Love the colour criss cross at the back. Makes it an unusual feature to break up the white. Very comfy and true to size

At first, the colour was too bright, but now I like it more and more. It is my morning exercise and breakfast outfit. It makes me feel younger. Love it.

So these were one of my first pair of leggings from fabletics and wow they give me such confidence, I can do squats all day and the only thing that would give up would be my legs as these leggings are brilliant. Also been washed so many times and still brilliant white.

I wasn't sure at first about having white bottoms, but I'm glad I chose them - they are really comfortable and have good stretch without being see-through.
