There are certain things friendship asks of you, and if you are lucky, they are specific and easy to fulfill. A school pickup. A last-minute opinion on a text message. A strong no on a questionable cosmetic procedure. Recently, it was a request to swap luggage in Nashville. My friend on her way to Barcelona asked if we could swap suitcases: my for her oversized, albeit chic yet check-in-only . All so she could glide through international travel lightly, while I sherpaed the aluminum biggie back to Los Angeles. Of course I said yes, because this is what friendship is: agreeing first, then discovering the true scope of the assignment later, as in the auxiliary cargo that came with. Her cowboy boots, for one. A big buckle belt (yes, that one). Great . Various Nashville artifacts destined to stay west of Greenwich Mean Time. If I were negotiating terms, I might have asked for one small reciprocal favor: let me pack the carry-on she took instead. Because I derive an almost unreasonable amount of pleasure from packing for other people, especially when the destination is better than mine. My ideal contribution to my Barcelona-bound friend would be: the on-sale look, below, for a sexy dinner out, this polished, goes-with-everything t-shirt (second pic, below), this tapas-friendly , this statement necklace, this peptide-rich moisturizer (key to a post-arrival glow), a few linen button downs (, , for sure, all 40% off now!), a fun bag charm, the pinstriped dress, silver bangles from , that comes with a belt to cinch other clothes, and the red ooolala too! PLUS: a bag, above, is essential: carry-on in spirit, deceptively roomy in practice, and exactly what she’ll need for the inevitable Spain acquisitions heading back to L.A. (preferably without deputizing another friend to haul them home!). Adios!
