Perfect for work! I use it for laptop, charger and few items necessary at work. I have a few blocks to walk from parking to work location and this bag has replaced last backpack and purse. Much easier to carry one item than two or more. Plus, it has enough room if you need to use it for clothes and toiletries (road-trip) or carry-on.

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.
