Undergarments for the bride!

Hi ladies! Can anyone tell me if the sticky bras are even useful? My gown is a bit more shear on the top part of the gown, so straps are a no go.. I’ve never used the sticky bras and if they do work can anyone recommend a brand to go with! (In the picture above I had to order a size slightly bigger, this one was the tighter one.. so the girls are a bit more out😅) but when trying on the dress they had me wear a strapless, plunging corset that was white and from the back you could see it so that why I’m trying to see if maybe the sticky bras would work better for me.. maybe I can get some input from anyone, that’d be very helpful! I almost forgot to mention that the dress has built in cups, they’re a bit noticeable in the image. So as much as I can, I’d like to not add too much in that area to add more attention and throw off the whole look.. thank you in advance to anyone who responds!
