How can I look thinner in normal clothes? (H-shape)?

I have an H-shape. At the beach, when I wear a swimsuit, I look fairly fit. My four pack and everything shows a bit ) and I have an actual waist. However, when I put on normal clothes, I look 20 pounds heavier. If I wear tight clothes, I feel like my belly fat is showing too much (it's on the bottom, hence not a 6pack) If I wear loose clothes, it makes a tent with my bust. What are some fits that I could wear that will make me look thinner?
