Supportive and true to size
Size: 34G, Color: Beige - Unlined
I really like the quality and fit of this bra. My only complaint is that there is no padding at all so I have to be careful if it's cold.

Cooling and Sleek Feel
Size: 42D, Color: Glaze Purple - Unlined
Fits true to size. A little snug at first but the fabric eases up and relaxes as you wear it. And that’s true for the cups too. It loses its firm hold as you wear it. Don’t size up if it’s tight at first. For summer, its a very cooling lightweight sling. The fabric is sleek, smooth and cooling. (Not peached or padded) Doesnt offer much lift or shaping, but good enough for cooling comfort.

Won’t buy again. Unfortunately.
Size: 38F, Color: Beige - Unlined
The bra its self is comfortable. But it didn’t hold up. I wore it a few times a week since I got it and now hardly two months later the underwire is stabbing me.

Skims dupe
Size: 34DD, Color: Black- Unlined
This bra is amazing. It fits perfectly and is super comfortable throughout the day, providing great support without excessive padding. I’ve had this bra for a while now and have had no issues, and no wires are sticking out on the sides which tend to be a common issue after long wear of a bra, but not with this one I think it’s a great skims dupe

Perfect everyday bra
Size: 38D, Color: Beige - Unlined
This is by far the most comfortable everyday bra I’ve ever worn! The fabric is soft and breathable, offering just the right amount of support without feeling constricting. It’s perfect for all-day wear, and I barely notice it’s on. The fit is spot on, and I love that it’s simple yet functional for everyday use. It holds up well after washing too, keeping its shape and comfort. If you’re looking for a bra that combines comfort and practicality, this one is a winner!
