Defective
Super cute bag, unfortunately it was less than functional.
The main zipper cannot zip up completely, as it has been sewn incorrectly.

My bag strap pulling out.
Color: Camel, Color: Camel
I got this bag as a gift from July and started using it in the middle of September for work. I love it but the left strap is pulling off. I am very disappointed.

Comfy and supportive
Love it! Very snug and supportive. I am 5‘6“ 188 pounds. I am wearing a 34H and it fits perfect. Will definitely be adding more colors to my collection. Hopefully they add the HSIA Delia collection that are similar to these, but have printed options.
