Misses Kisses Bridal Bra Kit - Need Help!

I haven't had my wedding yet but I do have this bra lol. They offer webcam fitting to ensure fit- I'd take advantage of this to make sure it's right. I find my breasts are pretty sore after wearing mine for an extended time period. Try wearing yours all day, if possible under a shirt that has a similar cut to your dress (low back, strapless, sweetheart, etc.?) Try dancing, too!
As for if it'll show- you'll only know once you try because every body and dress is different. Definitely try them on together and take what you plan to wear day-of with you to your seamstress alterations appointments.

I have them! My weddings not until May so I can't tell you how it was for the wedding day, but I've worn the bridal kit one for a whole day before and it held up perfectly. I did decide to go with the Shallow bar instead for my dress as that feels a lot more secure to me than the Bridal Kit one which is like a deeper/longer bar. I've tried on the Bridal one under my wedding dress (form fitting), and it's not "visible" but it verrrry *slightly* made it look like my dress had a built in boning in it (it doesn't).

Oh and I bought the sweatproof/waterproof pads because they are WAYY stickier and I don't want to worry about sweat when I'm dancing!
