For pants I tend to wear tights with a pair of shorts over them. Super comfortable, lightweight, and can pick up either.
For shirts I usually end up wearing workout tanks with a built in sports bra. They hug my chest pretty tight so when I bend over no boobies show. Mine go down to my hips but if you don't want that there are some that go down further. Dankskin(or something) sells at walmart, and i've had no problem with the shirt shrinking(and I wash each one twice a week). I've had them for a year and still going strong ^_^ And they form to your body and smooth everything out, even if they are skintight
very comfortable to work in as well.
