CU math instructor Delsie Khadem-Ghaeini noticed that most women, including herself, seemed to prefer a stretched-out T-shirt and shorts to most of the overpriced, body-squishing fitness wear out on the market. So she put two and two together and came up with VivaDiva, a comfortable, wearable women's sportswear line that she "re-engineered," as the scientific Khadem-Ghaeni likes to say, rather than designed. Fashioned from moisture-wicking and anti-microbial yarns, the resulting tops and bottoms are ultra simple, functional and roomy without being frumpy, and they come in solid colors that anyone can live with.
