When I received the invitation to join , the increasingly popular swimwear brand, at Nobu Los Cabos in Mexico for a weekend of sun, surf, and (endless!) sushi, I felt like the lucky caller on a radio show, winning an unbelievably awesome prize! Of course, I replied yes and even did a little victory dance when my plane touched down on the tarmac. I went on to say yes to lots more: heaps of guacamole, morning beach runs, day to night pool lounging, water workouts, a surf session at Cerritos, plus more spicy tuna rolls than I care to count. I also indulged in multiple outfit changes each day, thanks to the surplus of swimsuit and activewear options, all provided, of course, by Left On Friday. In case you didn't already know, the five-year-old Canadian-born brand has nailed the multi-functional, stay-put --rendered in a zillion mix and match colors, butter-soft, compressive fabrics, and flattering fits--that has pretty much everyone I know obsessed. Launched by former Lululemon design and marketing execs, the line has recently expanded into linen , (that I now swear by and you can see why below in the pics!), and , all masterfully designed with comfort and versatility in mind. My favorites are the , which can double as sports bras (my sis ran in the one-shoulder version one morning!), , and matching and that can be worn together or separately. Herewith the highlights!
