Great staple slip dress
This dress is more on the expensive side for a slip but it is SO cute and flattering. The low cut back is stunning and the material is soft and has some give to it. Super simple and sexy.

True to size
Size: 9.5, Color: Tusk
I want to start off by saying I ordered a 9 and 1/2 and these fit perfectly so they are true to size. They are fairly comfortable in the heel isn't too high but is wide so they're very stable to walk in. They look great and can be styled in a variety of ways I have worn them with jeans but also a nice sundress and it works both ways. I've been wearing these for several months and they've held up really well and still look great.

Daughter ranks it 5/5. I rank them 4/5 due to heel comfort.
Size: 8, Color: Black, Size: 8, Color: Black
My foot is 9.44 inches long which usually places me in a 7.5. For this chart, it suggested the size 8. It's a perfect fit. The back zipper is easy enough to use. You don't even really need to undo the top strap once you have it adjusted to your preferred spot. My foot is narrow to normal around the heel and I'm wider in the toe box. These heels accommodate that well. I have plenty of room around my toes. The toe strap isn't smashing down either. The shoes seems well-made. The straps do not have a threads hanging. There's no sloppy glue drips around the bed. The bottom is strong and the heel is solid. I'm not a huge fan of thicker/chunky heel looks usually. I like the skinner heel styles mostly but ... there's a big positive to the chunky heels. They're very easy to walk in. Great heels for non-formal occasions. The bottom is not slippery. The cushioning around the toes in very nice. My only complaint is that the cushioning by the heel feels inadequate- especially at this price. It feels like you're walking on a block of wood. For that reason, I gave them to my middle schooler. She's thrilled. She pranced around the house in them testing them out for herself. She adjusted well to walking in them and she finds them comfy.
