If you take a lovely route, just wear white inside, preferably a sling or a sports vest with a pattern on the chest.

If you take the sexy route, you can wear a coat in a vacuum in a few days ~ wear a bra or nothing. Of course, you may not accept this style. . Then I suggest you wear a contrast lining, red with green and blue with contrast. You can try to match it.

You can also wear a skirt with suspenders and a suit outside, which is also very nice.
