The first step to keeping your skin extremely soft is to use an exfoliating body scrub in the shower. There are so many on the market. Some of my favourites are Fresh Brown Sugar Body Polish, Bliss Lemon and Sage Body Scrub, Kiehls Ultra Moisturzing Buffing Cream With Scrub Particles. They will get rid of dead skin, leave your skin uber soft, and leave it ready for moisturiser or bronzer. 
The next step is to moisturise!!! Very important! Your skin gets dehydrated very fast so its important to lather up. The skin on your body is different than on your face. While we wouldn't puts tons of moisturiser on our face, we would on our body. If you have some acne on your body, perhaps try a moisturiser that is medicated. Some good lines for this are Kiehls, Dermalogica, and of course Proactiv which will give you the fastest results. My favourite moisturisers are Kiehls Creme De Corps (The king of moisturisers!), Bliss Naked Body Butter, Dermalogica Body Hydrating Cream, and Fresh Lychee Sugar Body Lotion. If you find that any of these are to thick, each line makes variations of these creams that are lighter. So try switch it up. Maybe use the thicker one before bed and the lighter in the morning. See what works for you, but remember to moisturise every day and your skin will be left feeling soft and silky!
