I loved this little top and I bought it but beware as it runs big! The straps are not adjustable, the ties are sewn into place. SO that's nice but not adjustable and I did find that they slipped down at times. I you have smaller chest, definitely size down. I'm in the medium and it fits plenty loose! I'm in the large of the skirt, it's a generous loose fit in the waist. No need to size up unless you need length. LTKFindsUnder50 LTKFindsUnder100
