That is such a difficult question for me!
By now I have so many bras I could start a used lingerie store if such a thing existed, just with my bra collection, never mind the panties.
I have so many to choose from, that it is impossible to say which one, or even which model or brand, is my favourite.
What I like to wear depends on a lot of things and quite often I pick something that at least resembles something that I saw on a GG I spotted at work or in public, whom I thought to be well dressed.
It gives me a kick to see a woman somewhere and thinking that I have something similar or almost exactly the same, which is why I often buy stuff that I've seen.
It enables me to feel that I wear something that a GG would really wear, instead of something that just fits my fantasy.
Currently, I mostly prefer bras that cover the faux breasts that I use as much as possible, so you can't see that what I have in that area is a complete and utter fraud.
I own a couple of Triumph bras, minimizers and such like, which I think are what you would call full cup or almost that anyway.
I also have a few from Plaisir that also manage to cover my faux breasts.
Right now I really, really love bras that have these little rings in them on the back, especially ones that have that ring high up.
Why? Because I noticed them on a number of women and suddenly that is what I need.
But I also have a lot of bras that don't cover my fake boobies entirely, so I combine those with clothes that completely cover the revealed material.
I would love to have something that allows me to reveal cleavage and the upper part of a boob without looking completely fake, but does such a thing even exist?
What I use to replace that which I do not have?
Well, I cut off the cups from two bras.
One bra was pretty tiny, but had these kind of sacks behind the cups where you could discreetly put some filling into.
I stuffed those things like it was an stuffed turkey about to be put into the oven, using some strips of fabric from a dress that I had bought that turned out to be the wrong size.
Instead of fabric I had earlier used silicon breast enhancements a GG might use to give her a little extra in that area, but at one time I fell asleep with them and somehow crushed one of them, so it burst and leaked icky silicon everywhere that was such a pain to remove that I just threw out everything that had been contaminated, including a duvet.
I have been avoiding them ever since, even threw out the remaining ones that I had, they were never visible anyway and their only advantage was that they had these tiny nipple like things.
The other bra was a bigger push up bra, with built-in padding.
I put the bigger cup on the smaller one, then insert them into my bra and twist them just right.
If the bra covers enough of them, it results in two nice round shape, that resemble breasts if you don't look that closely.
There is an area at the top and basically there where the cleavage is supposed to be that is missing, an opening.
So far, it is the best I have and if I adjust my wardrobe accordingly, it works for me.
Best of all, they feel pretty natural to me, similar to the silicone stuff, although granted, I am regrettably not exactly very experienced groping actual breasts.
Breasts are awesome, so I miss that and make do with groping my own..
Oh yeah, this is also, of course, a pretty cheap solution.
Not that I really care about cheap any more at this point.
