Bra or duct tape???

Maybe a built in bra would be the best.

Im with @Chivy it Sure will and they tuck your nips so its not directly attached to them. I made a post about this before I didn't know this was a thing until I had it done.

Another option instead of duct tape is a horse product called "vet wrap" - less painful and easy to remove and will keep those girls sucked in. Also comes in lots of colors and is only $2/roll. I have a friend who needs to use it on occasion and swears by it

All I can think of is this scene from The 40yr old virgin. Ouch

Since you're doing a custom dress, I'd hope she'd be able to build in serious support - it'll certainly take more than sewing in old bra cups though! If the whole waist part is structured and the front part has some corset-like boning underneath, that'd be ideal I think.

I do love medical tape as a quick and dirty bra solution though!

Amazing. I love duct tape, but please no for a June wedding! Save it for a less sweaty time. Use something that is deigned for skin!

Try Sneaky Vaunt or another popular backless/strapless option. I have heard nothing but great reviews!

I'm pretty busty myself and have tried them, they're pretty magical.

I suggest the tape. I'm not seeing how a bra of any kind would work

If you're thinking tape, I second pp and say athletic tape! Look into K tape. It's typically used to hold muscles in place and a lot of athletes use it, even pros, so it's meant to hold up well against sweat

I came right to posting. A girl friend got married. Boobs to die for. Duct tape held the girls in place all day and into the night. When her and hubby got back to their room, she was in tears as he literally had to rip the tape off her chest.

No sex for a couple of days.

If you have to do tape, I vote kinesio tape.

Look into a V shaped bra

I've been in that dilemma for a bridesmaid dress and used athletic tape. It gets the job done, but be absolutely a million percent sure to cover your nipples so NO adhesive touches them- made that mistake, and OUCH!!!!

I know I'm a bit late, but if you couldn't find a bra I'd recommend athletic tape instead of duck tape. Its a bit easier on the skin and is less likely to leave awkward crease marks on your breasts (coming from experience). Plus athletic tap is often cloth and won't give the "rippling" effect duck tape might.

Not sure if you are still on WeddingWire since it's been a long time since your reply but I have to ask what brand of tape you used? It sounds like exactly what I need?! Thanks!!!
