With my c cups in, chest squeezed and lifted up and leaning forward I can make it look like I've got real ones and a hand full too.. I once had pecs now moobs probably A cups .. so happy with my separate breast forms.

I use B size - often with a C cup padded bra As I have a bit of my own flesh and slightly pigeon shape chest So the breast form sits well inside the bra - you don’t want any plastic showing if you have cleavage on display.

search on Amazon for Vollence self adhesive breast forms. They are around £35. You still need a bra but quite unlikely to fall out of a normal bra.

I've got a pair of those teardrop ones too (B-cup, for the record!) and find them perfectly adequate for most things I wear, although I wish I had a more 'meaty' chest that I could push up into a cleavage.. I've looked at the breastplates and am tempted, but can't convince myself to part with that amount of money - partly because I wonder just how sweaty you get in them and have visions of myself then trying to extricate myself from it without tearing the material or dislocating a limb.

I have used these double-sided adhesive discs to attach my current forms to my chest. They work very well although I don't think they would stay put indefinitely without a bra or other support, but I've worn them all day without them falling off, and the adhesive film peels off the breast form quite easily. You do have to make sure you use the correct side of the disc as they use different adhesives on each side.

This is an interesting topic as I'm still trying to create what looks like a natural cleavage. Like Davina I bought a pair of dd teardrop forms first which were an amazon factory deal (damaged box but otherwise fine). They are good but unless using a pocket bra an absolute liability as can slip from a normal bra if I lean/jiggle to much. Certainly not an ideal if I am to ever leave the house. I am currently looking at some self adhesive forms of the triangular shape. I'm 6'3" high and a size 14 but feel the dd option might be a tad to big, so possibly a B or C cup. Anyone else roughly the same stats and can say what looks, feels natural? Also what bra size tricks do others use to find the best fit, any recommended makes. I've heard going for a shorter back size and using an extender so the cups are closer, I guess due to males chest being wider generally? Ta 🤔😁 All answers appreciated.

That made me smile. Puncturing a tit with a stilleto heel 😆😆. I put my shoes in bagged pairs and keep the forms in the box so hopefully I won't get a puncture. I've seen the breastplates. A few girls on a Crossdressing Reddit seem to wear them and they do give good look, especially for lower cut tops and dresses. I don't tend to go so low cut with my clothes so I've no real need but I'd certainly consider giving them a go. I suppose the boobs won't move around so much, my teardrop ones can move around a little bit, especially if I get a little bit warm. I've recently watched a YouTube vid that suggested wearing underwired bras rather then non-wired to give better support. I've also seen another YT vid (Heidi Phlox??) that recommended wearing a strapless, lightly padded bra (with invisible straps), and maybe even cutting the bra open to slip the forms inside. I'm slightly sad in that I can't stand bra straps on show so using invisible straps could be a good shout. I've had a wide selection of bras in the past, mainly black and some very pretty ones, but I got rid of most of them years ago. Slight regrets now but way too late to worry about.

You can get one of these things which if you match skin tone I've seen effective for cleavage but some just look silly.. I've got a pair of silicone boobs similar to the below .. The above will cost £100+ mine were £20 off amazon or eBay.

My first set I got from another t girl who was purging a new set of DDs .. They were nice but in packing them in a bag with stilletoe heels they punctured the one tit.. So ordered new from Amazon in a C cup which looks better on me.. And they'll do for me..
