I have a nike top like that - but it doesn't have a band around the bottom, I do a semi tuck, which give me some modesty when I do press ups and planks, it's my favourite top in the summer. I have one from Gap too with the band around the bottom but it rides up and annoys me.
Ronhill make great running tights - with a back pocket big enough for an iPhone. And as far as I know they are not see-through when you squat. If you are looking for something gorgeous - Lululemon running tights have a lovely gather detail at the ankle, they are on my US shopping list!
