Used to wear boxers or scrubs, but a couple years ago the GF bought me a couple pairs of RL Polo at the discount stores. The patterns I have are all neutral stripes on blue. The pants are not sewn with a cuff, but I usually roll them, as they are a little long. The tops came as a set with the bottoms, and are enormous, so I usually just wear a cotton tee. Sometimes the GF uses the tops as a nightgown. Pretty sexy!
I pretty much get into them when I get home from work. If I go out I change clothes anyway. We do not really have unexpected guests, so it is no big deal. I find that this arrangement really helps me to mentally/psychologically separate school/work from home life.
I have been looking for the perfect silk dressing gown with either a navy, burgundy, or bottle green base with a pattern like micro paisley or polka-dot.
