stiff like cardboard tops of shoes
Size: 5.5, Color: Natural Nbpu
These shoes are good enough quality and cute cute - even fit great, EXCEPT the faux leather top (part that encircles your leg) is so stiff, that when you walk, it cuts into your leg like hard cardboard making it difficult to walk comfortably. I do like them otherwise, but can't stand the hard, unbending top of these shoes.

Sizing.
Size: 10, Color: Natural Nbpu
They run big, I usually wear a size 9 wide, but since they didn't come in a wide, I chose a 10 and they fit comfortably width wise, but they were too big otherwise. I would recommend letting viewers know if it is a wide shoe to let buyers know, to better serve the customer on what size to purchase, other than that, I loved the shoes just wish I could've kept them and worn them for my event.

Flattering, Comfortable, and Perfect for Everyday Wear
Size: Large, Color: Black
This Amazon Essentials tiered midi dress has quickly become one of my favorites! The fit is relaxed but still flattering — it flows nicely without clinging, and the tiers give it a light, feminine shape. The fabric is soft, breathable, and easy to wash, making it perfect for warm days or layering with a cardigan in cooler weather.
It’s one of those rare dresses that works just as well for casual outings, errands, or a dinner out. I’ve even worn it to work with sandals and a denim jacket. The length hits just right (mid-calf for me), and it has that effortless, pulled-together look that’s hard to find at this price.
If you love comfy, versatile dresses that make you feel put together with zero effort, this one’s a winner!

100% cotton dress
Size: Large, Color: Navy, Size: Large, Color: Navy
I really like the fit of this dress. The details are feminine with top ruching and gold button on the neck.
The dress is 100% cotton sateen fabric and is on the thin side and may require a slip if you get a light color. I purchased this dress in navy and black with floral. It has a defined waist and comes to my natural waist. A tiered aline skirt and cap sleeves a cute detail on the trim.
I can dress this up with any color belt to define the waist further.
I purchased a size large and it fits well with a bit of a roomy waist. I think of o got a medium it maybe to small on top and waist.
I got this for $15 on black Friday.
Perfect spring and summer dress. Can be a fall dress with tights and a sweater.
My only criticism of the dress is the tip of the zipper is not sewed in to the dress and it sticks out when you lift your arm. I did stitch the material into the seam and it only took a few minutes.
