I went to wall mart and bought 5 pairs of scrubs, all at once. I have light blue, dark blue (now my school clinicals w/patch), maroon (which everyone jeers me about being pink), teal green, and my favorites are the whites. I love the whites the most. It just goes with being in a hospital, even though there could be thousands of fomites on it :-(
All my scrub pants have the elastic waist band. When ever i wear the once i have aquired from the hospital, I feel like they are risque, because the material is pretty thin, and if i bend over or reach for something, you can see my shape.
My cross-trainers are the star everytime I wear them. they are Roc-Shox, super supportive and comfortable, and I only wear them to work or to aerobics. they look like they have springs on the heals, and are yellow.
