The Bumbas Boost Inserts work best with tight fitted, structured, tops and swimsuits.
They are not designed for loose fitted clothing, such as t-shirts.
We suggest you choose the size closest to your current bra size.
If you are in between sizes, size up for a more dramatic lift or size down for a more subtle lift.

amazing and good quality and easy amazing and good quality and easy to use
I loved them!!
They arrived relatively quick and they were super easy to put on. i am normally a DD so i got them in the size D and it worked out perfectly, you cant even tell im wearing them! i was shocked at the amount of lift they gave i mean look!! Big titty friendly!😩
They stick great, wore them to the river in my bathing suit and worked perfectly , I rinsed and reused the next day , did it a couple times and still good
i love them. they do get uncomfortable after some time but they work well. i found they work best with a bra and a tight shirt.
I wish I knew about these sooner! I have always been self conscious wearing a bikini because there’s no support and I couldn’t hide behind a push up bra.. LOL. I love that these stick to your skin and your bikini. You’ll be happy you have them when you need them!
Loved them! Such a noticeable difference! Won’t come out of my swimwear either!
I have Easty Westy set boobs so it was cool to finally see cleavage as an A cup!
I am not sure if I’m doing it all the way right because the outer edges don’t stick down if that makes sense. I don’t have any showy tight shirts so I’ve only tested it with a bra which they worked well together. Even with that I got to see my full boob potential!!

Ok. Listen up right now. I’ve tried them all and these are THE BEST. These ones are the real real deal like do not move. They stay on through sweat, water, all the above. They don’t stick out on the sides or top at all and make your boobs look so naturally big not like fake big. You cannot tell you’re wearing them at all. I’ve been searching for soooo long for ones to wear in swimsuits and I’m so freaking happy I found them. Save the damn boob job, get these. I’ll wear these things till I die
I’m happy that there’s some nipple covers for us dark skin girlies!
Good product, will serve for what I need. I tested and the glue is good.
I went to an edm concert with hard dubstep music. I was head banging and jumping up and down so hard I think my brain dislodged in my head. I was soaking head to toe. But my Bumbas inserts faithfully stayed with my tits all night and were still sticky when I came home. I would 100% recommend and buy again
These are sensational. Literally like a $30 boob job. I’ve never felt so confident in my bathing suit and tops. They do not budge once you put them in. Many thanks for a great product!
Make sure you buy pasties with this and even look online for a tutorial on how to put the tape on. It held up nicely, even though it’s so sticky my skin felt sensitive when I took it off. Works 10/10 but may be 6/10 comfy to wear and pretty annoying to take off.
Good shape and sticks well. Delivered quickly to the Netherlands.
Beautiful
Everything is as described. arrived quickly. recommend!
The cups are quite dense, the shape will be held perfectly. Not sharp in shape, look natural, with them my flat chest looks great.
Product is good and was very useful
corresponds the description. color and transparan is so-so. May try to order darker silicon as this is a little bit see-through nipples in a white shirt. Also, size for my B cup i would recommend 10 cm instead of 8 cm.
quick delivery
This is the best sticky bra i've ever owned, and I've tried several different kinds. It stays in place all night and gives me great lift without adding a huge amount of padding. I've worn them with so many different tops. So glad I found these!
One side with silicone (sticky) the other pleasantly smooth. Not yet used but I think it will be good
