I initially got this leather backpack (available in 30 colors) for travel, but it has since become my go-to everyday bag. Why? Several reasons: It transforms from a backpack to a purse thanks to its various strap options. It has side pockets, a front pocket, and a roomy interior with multiple organizers. And, best of all, it opens from the back rather than the top, meaning you can see the bag's entire interior at once.

The Drop's Avalon shopper tote has several features that set it apart: It has asymmetrical, pull-through straps as well as a faux pebbled leather exterior in your choice of five colors.

Reviewers can't believe the $32 price tag on this Anne Klein bracelet watch: "Chic and looks far more expensive than it actually costs," one wrote.

It's a bit bigger than your average clutch, making it perfect to hold your phone, makeup, and wallet, but it still fits effortlessly in your hand with its squared gold-tone handle. (It also has a hideable 22-inch chain for use as a pocketbook.) If you don't love the leopard print, you can get it in eight solid colors.

Because it's made from 100% cotton, this KIRUNDO dress is cooling and breathable enough for hotter weather.

This blouse from Floerns takes tons of the hottest trends — knot-ties, cropped silhouettes, bell sleeves, deep V-necks — and combines them into one to create this showstopper.

At first glance, this Bestland finishing stick looks like a tube of mascara — but it's meant for the hair on your head rather than your lashes. Its plant-extract-based formula smooths down frizz and flyaways (without excess grease or unwanted crunch) so you can touch up any hairstyle, up or down. "What is this magic!?" asked one reviewer, who has "tried everything" to tame those baby hairs. "This product works. I mean, it WORKS."
