Hi Victoria,
There are products to hide beard shadow. The most extreme I know is called Dermablend which, I believe, comes in a creme with a setting powder. It's made to not rub off. This is definately needed for those with dark hair. If your hair is lighter, you may just need a more opaque foundation. I would suggest trying the Max Factor Pan stick in the appropriate shade. You can get details on covering the beard on
http://www.yvonnesplace.net/head_toe/groundwork.html or many other sites, mostly ones that deal with crossdressing. Your sisters have posted a lot of information.
Make sure that you start with a smooth shave.
Breast form attachment (or removal)
Well, ease of removal depends on how well you want to attach them.
There are some forms made to attach using velcro. These require you to attach the loop side of a velcro piece to your chest. The hook side of the velcro is on the form. This does allow easy removal and if you can hide the piece on your chest can be easily reattached as desired. (I never had much luck with these. and I don't know if they were really desiged to go bra-less, if that is what you want.)
There are some forms with an adhesive on the back which are mostly to keep them from moving too much in a bra. I don't think these were made for going bra-less.
Many places that sell breast forms sell double sided tapes, and often include a supply with your first purchase. These are very strong adhesive tapes and I think probably work well with smaller breasst forms but with me being a big person, they did not work as well as I expected, or I didn't use enough of them on the form.
My favorite is medical adhesive (I use Hollisters spray). However, you definately should be committed to wearing the forms for awhile. I don't suggest using it for just a few hours (1-2). Medical adhesive should be removed with an adhesive remover. If you "peel" them off you risk some pain to your skin and doing so could damage the form. How well the forms stay on depends on preparation (shaving and removing skin oils), and how much adhesive you use. I don't thoroughly coat the form with adhesive when I put on my forms, usually put it around the edges. I find that I can go about a day and a half before they come loose, which I think is caused by the growth of chest hair.
Any further questions, feel free to PM me or ask in this thread.
