This product did a good job for me! I wear a 34I, and had a low-cut dress for a wedding. I couldn’t wear a regular bra, but the classic cut bra pieces plus a couple pieces of tape really held up! They stayed in place all night, through the whole ceremony, dinner, dancing, and after party. I did find that I had leftover sticky stuff where some of the tape was for a while, which was difficult to remove. Overall would definitely recommend the product!
