Watch
Color: Gold band&Gold dial
I was not impressed with this watch. It did look good. It was absolutely gorgeous. The only problem is it didn’t work. We tried everything in the world as to following the directions, but nothing would make this watch keep correct time. So it had to be sent back.

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 They work especially well in office environments where a full formal shoe feels too stiff or outdated.

New Favorite Work Shoe
Size: 9.5, Color: Black/Ivory
These Cole Haan Grand Crosscourt Daily shoes have quickly become my new favorite work shoes. They’re incredibly comfortable right out of the box, with just the right amount of cushioning and support to get through long days on my feet. I love that they look sleek and professional while still feeling casual enough to wear anywhere. The build quality is top-notch—durable materials and solid construction that make them feel like they’ll last a long time. Overall, these shoes strike the perfect balance between comfort, style, and practicality. I can honestly say I look forward to wearing them every day. Highly recommend for anyone who spends a lot of time on their feet but doesn’t want to sacrifice style.

Well Made for price and style
Size: 10.5, Color: Black/Ivory
Great fit and very flexible. I also recommend buying shoe savers when purchasing this product. To help with toes wrinkles. The pair itself is stylish and very comfortable. Any purchase of this product will be greatly satisfied.
