Although not fancy or for work, sometimes I will wear one of my darker pink t-shirts, no bra, and a short light blue denim pleated skirt.  The skirt will come mid thigh if I sit back.  Which reminds me I need to do some more stretching.  
Any way, this is comfy.  I do not wear this out though as it is not modest, worn as described.  But I may occasionally when I visit my sweetie, as I can feel comfortable like that with her.
