Really pretty. Everyone comments on it! The adjustability is most important as I have a large wrist.

Beautiful, But Functional Needs Fixed
Color: F-Rose Gold
The watch is beautiful, but the latch component doesn't snap closed. I'll return the watch.

Good comfort, quality and classy
Size: 8.5, Color: Black/Ivory
’ve been wearing Cole Haan dress sneakers for work and travel, and they strike a really good balance between professional and comfortable. The biggest advantage is how lightweight they feel compared to traditional dress shoes. Most styles have sneaker-like cushioning, so you can walk or stand all day without your feet getting destroyed. The design is also versatile and look polished enough for business casual outfits but still casual enough to wear with jeans. They work especially well in office environments where a full formal shoe feels too stiff or outdated.
