Casual, both good and bad.

Casual or professional in the workplace, both have pros and cons.
One of the greatest companies to work for allows their employees to wear anything, while it can be said that looking professional will get you farther.

I think the one thing to consider is that if you are working for a company that has a casual dress code is whether or not you have the job of your dreams. If you are looking for a comfortable position then you'll be fine to just drift through the casualness of the office. If you're hoping to be more than get noticed in an environment where everyone is casual and you look professional.

Dress for the job you want.

One thing I've learned researching and writing this blog is that your clothing and attire choices reflect on others more than you think. Most people do not even realize that you judge people consciously AND subconsciously.

On the surface most people see a neatly dressed person and possibly think nothing other than that. Below that initial reaction I think most people are also thinking things like "He/She looks fantastic - this is someone who obviously knows how to make a first impression" - this would make you the perfect candidate to impress new clients/customers. Someone might also see your outfit as well put together, giving them the impression that you are very well organized and have a keen eye for putting things together; which might help with landing that great project that requires attention to detail.

If you dress 'for the job you want' you may find yourself closer to achieving that position. I found this great link to a free book online, it reads like an infomercial but it has some great ideas.

This free book shows you how to dress for a job interview. Dress For The Job You Want is a basic guide that helps you put together an outfit for a job interview and present your best self. You can download your copy here.
