I'd like to say that I prefer basics because they never grow out of style and then pretend that I'm a classic dresser that way, but I'd be lying. I'm now comfortable enough with myself to admit that I will never be fashionable and frankly, I don't give a sh*t.
Instead of being fashionable and following the trends, I try to go for clothes that flatter my body type and fit well. That means playing up my slender figure without drawing attention to my less than defined waist. Through the years I've come to realize that I look best in loose tops and tight fitting bottoms, or the reverse, tight tops with loose bottoms. And with my mommy pooch, I mostly favor loose tops these days.
Also, how can you go wrong with basic pieces? They go well with everything, they age gracefully and are every frugalista's bestfriend.
