I learned years ago the importance of recognizing acceptable workplace attire the hard way. I am so happy I work from home now. I don't have to worry about how people are going to perceive me or judge me by my clothing. I can work at home in a pair of jeans and a t-shirt, and do not have to spend my money on suits I don't even like to wear. But trust me I know that when I am out in public how I look is going to affect the opinions people formed about my company and me as a person.

Plus-size clothing needs to be modeled by the people it was made for, plus-size models. Aesthetically clothing designed for a larger person does not fit well on a smaller person and visa versa. A princess seem line dress looks great on a person with some shape, an A line dress looks good on a person with very little shape. That is the way it was designed. A plus-sized person can look just as sexy or hansom with the right clothing as a not plus-sized person, some times even more so.
