Small-breasted MM can't hold up completely if she only wears clothes with chest stickers.
I suggest you buy the invisible silicone bra with the front button.
It can concentrate the plasticity of the chest well.
Body-shaping underwear generally has shoulder straps, which is obvious if you wear a tube top or a skirt with suspenders.
Of course, if it is an off-the-shoulder dress, it is also a good choice to wear body-shaping underwear.
I hope I can help you.

Body-shaping underwear without shoulder straps, MM with small breasts, is simply not acceptable. What kind of contact underwear is very useful? You can buy a thick one, or wear two at the same time, which can have a good effect.
