Site Navigation Issue

Site URL: https://bronze-orchid-etpn.squarespace.com/

Hello, 

See the screenshot attached showing my website navigation circled in red. You'll see the last folder called "Collections" is being pushed down to the second row. I would like all nav links to be in one row vs. split into two rows. How to I customize my site to decrease the padding on the left and the right side of my navigation to allow all links in one row? 

Site password is "1234"

Thank you!!!
