Outfitof the Day for Spin

I haven't been to the gym or running for over week because of my chest cold but am finally getting back. My OOTD (outfit of the day) for spin today is a Sprinkler Blue Scoop Neck tank, new black wee stripe Wunder Unders and a matching Sprinkler headband. I hope this spin session puts my cold to rest once and for all. I am doing a Pure Barre class tomorrow with some friends. I need to figure out what to wear for that.
