One of my favorite design duos is the Proenza Schouler team. Their attention to detail is brilliant and their latest accessories are a must-have for any girl on the move. Lately, I’ve been trekking and traveling with Proenza Schouler’s PS1 medium leather bag in khaki. I love that it looks a bit like a briefcase and the strap is removable so it really can transform itself into a mini case! Buy it in a neutral color and it can be worn with just about anything or splurge on a brilliant bold hue to stand out from the rest.
