Thank you for trying this pattern! I made this top for cute summer beach vibes! You can tie the neck and back pieces to fit how you want.
I wrote this pattern to fit me (S/M). It may be able to be modified to fit L/XL by adding more increases in the increase rows, however I haven't tested it myself so I'm not sure how well it would come out. Make sure to do it symmetrically (ex: if you do 4 increases on the first main piece every increase row, then make sure to do the same on the second main piece).
Happy crocheting! <3
