    The world’s best top!

    This is my 4th time buying this shirt! One for everyday that’s how much I love it.

    This shirt has incredible wash and wear qualities. Super comfortable and worth the investment as a staple in your wardrobe

    Love!

    Super soft, very flattering, and washes well. I did have to size up, normally i wear a medium but the modal seems to run small. Will be buying more!

    Modal Rib Long Sleeve

    This has become my favourite layering top. It's perfect under a sweater on colder days. It's lightweight and breathable. I bought my usual size and it's fitted, and not too long. I don't know about the other colours but the white is slightly sheer.
