If you are a 1/2 Size .... go up!
Size: 8, Color: Black, Size: 8, Color: Black
I love it! I wear heels everyday and these heels are great! Very comfortable since the heel is not to large also still sexy since it’s a stiletto! Only down is that they do not have 1/2 sizes and I am a 8.5. I got 8 based on the reviews but I knew better I should have went for the 9. Not their fault so I didn’t lower the rating. Aside from that they are awesome!

Red clutch
Color: Red
The red clutch is of utter most quality. Looks like genuine leather and the magnets are very strong. You don't need to worry that the bag won't close. I absolutely love it!

Lighter than pictured, but I still like it. Mine arrived with some minor damage.
Color: Beige, Color: Beige
Update: I ended up returning the item since I couldn't justify keeping something that cost close to $40 and came with rips and damage. I was on the hunt for an oversized clutch that could hold a small cropped sweater for an upcoming outdoor wedding. I wanted a taupe/pinky beige color bag and thought this looked like the perfect color in the photo. Now that I've received it I can see that it's definitely more yellow-toned beige color and lighter than the shade shown. Still a nice clutch though and I bay still be using it for the wedding. It has a nice magnetic closer that keeps it folded in place. The included gold chain shoulder strap is super cheap looking and I won't be using it, but nice to have for someone in a pinch who is sick of carrying the purse around. Material is a nice faux leather and looks very similar to a legit Italian leather purse I own. My purse did arrive with some rips on a top seam and an indent in the front of the material. Not sure if I'll go through the hassle of exchanging or not, but definitely look your bag over once it arrives. I included photos with a standard deodorant for scale. The inside is wider than most foldover or envelope style clutches which is exactly what I wanted. Easily holds my phone, small wallet, some makeup items, a small bottle of ibuprofen, and a thin/light material sweater without looking bulky.
