Can i see what an item looks like on my character before buying?

In other games i have been able to view what every item looks like if i was to equip it before i buy it. Is there a way i can do this?

No yet but items preview is one of the future features to be added.

Thanks HEC. Just one more question, what do the small circles in the top right corner of each item mean? some are yellow some are red.

Those circles indicate the dye color on the item.
