Purses are like lipstick in that it'd be sort of silly to only have one. You need your red, pink, nude, etc. in accessory form because, practicality aside, your bag is probably your best indicator of your “current mood' to the rest of the world. But, if I had to pick one style that is the superlative in both form and function, it would probably be some iteration of the crossbody bag. You're busy, and so are your hands, so here are some options:
Muuñ Fille Straw Crossbody Bag : While a big straw bag can be a bit much, this tiny version is more palatable. Its straw is a neutral that will look pretty great worn with clean white t-shirts and lightweight linen.
Zara Leather Messenger Bag : Chloé's 'Drew' bag (dreams) has rounded bags feeling new again. This textured, saddle-like purse comes in a versatile color that's still way more interesting than standard black.
Alfie Douglas Leather Mini Shoulder Bag : Almost like a briefcase—I'm a business, man.
APC Half-Moon Bag : Flip that sloping, rounded shape upside down, and it looks just as cool. Swap tan in for your usual dark neutrals, and let the significantly more summery vibe rub off on you.
Maryam Nassir Zadeh Summer Bummer : This classic shape leaves plenty of room for storing everything you need with you at all times—because we all know that there's so much more than your phone, keys, credit card, and lipstick.
