During the winter I have increased my cup size to a B by using pumping techniques.

But, having purchased a unpadded bra, I realised that I am only a B with padded cups! I fill the padded ones nicely, but the unpadded one leaves a bit of a gap and provides no support.  I therefore ordered a pair of chicken fillets, and the effect was amazing.

I lifted my wobbly bits and nipples onto the fillets and it has been a revelation. I am fully supported, and I have got real cleavage. I can hold a pencil between my boobs. I feel like Marilyn Monroe, I am so busty.   

I have a pair of chicken fillets.  I call them my boobie boosters.  I love the way they make me look, but one time I wore them for six hours for an evening out, and they gave me a bit of a rash.  Not an allergy thing, more of a heat and sweat kind of thing.  (Women sweat from under the boobies, that might not be a problem for you).

I don't bother with them for outings any more, since a VS push up bra gives me all I need, but I love the way they fill out bikini tops that are a little loose, so I keep them for swimming.

Just make sure your bra is tight enough. I used those things when I was first transitioning and once when I bent over to get something the stupid things fell out and slapped the floor at Walmart. 😖😖
