We have been running a series over the last couple of months on the style staples that everyone should have. From the black blazer to the white shirt, tan tote bag to printed pants, maxi dress and patent loafers...we have it covered. This week it's the black bag and we have put together three options: one priced at €25, one costs €74 and the third one is €280. €25, at River Island This is fantastic value. It's a compact size, the cross body strap is perfect for ease of use and the gold details add a little touch of luxury. In fact, if we didn't know better we would think it's a LOT more expensive than €25. Fair play to River Island on this one... €74, at Topshop Topshop are fantastic for stylish staples and this leather bag is definitely a need. It might be a little pricier but if you prefer sturdy and functional to high glamour, then this might be the one for you. It's a piece that will stand the test of time which is exactly what you want when forking out those extra euros. €280 Marc Jacobs, at Harvey Nichols Oh Marc. While we're always on the hunt for a bargain, we can't deny the beauty of this luxe cross-body bag. The simple gold bar across the front is elegant and discreet. While cheaper bags look good to begin with, after a couple of seasons they start to show their age. Little frays and rips appear, seams burst and you're back to square one. This baby will last the distance and that is why it's worth the splurge.
