What I like in the call center is you can wear anything corporate as long as you have blazer when you go inside the call floor. So to those who are planning in the corporate world where there is no real uniform but anything corporate You can try a classy tube dress of course you should match it with a blazer or a parka something. Anyway the classy tube dress can also do well in parties .
If you are looking for a blazer, try the structured blazer because it can actually spruce up for any outfit that you would like as the inner or cotton pants.
Water color dress can be of ramp as well, yes it can fit in the corporate world as well. Match it with sequined clutch and or gold strappy heels.
