Get it! The Selma is a classic style. I own 6 large ones in different colors (malachite, sapphire, luggage, dark dune, coffee, heather grey). I rotate the colors by season. Malachite, heather grey, and coffee mostly in the fall/winter months. Luggage mostly in the spring/summer months since I have so many others that function well in the fall/winter. Dark dune year-round since it's a neutral taupe. And sapphire is outfit-dependent, but I mostly wear it with black and white.
I also own 2 MKC large Miranda totes (black w/shw & tri-color suntan/shell/ivory), 2 large Hamilton totes (black w/shw & dark dune), 1 large Sutton (tri-color luggage/white/navy), 1 reversible n/s Izzy tote (dark dune/black), 1 MKC Sedona messenger (luggage/coffee), and 2 Berkley clutches (gunmetal & calf-hair leopard print). As you can see, I love MK, own several bags in multiple colors, and I do use all of my bags. I seem to have something for every occasion.

If you love the medium black studded Selma, get it! I don't think you'll regret the purchase.
