I still work as male and have to wear one every day for work. Coming out in a workplace full of road construction workers and other homophobic, misogynistic manly men wouldn't be a good thing, if ya know what I mean, so I'm keeping my mouth shut until I've got the money I need for my surgeries.. I make very good money in a union job, and in this economy I just can't leave and get a new job that easily.
So, to hide my B-cup breasts, I wear a compression shirt that I purchased from
underworks.com. Works well, mushes everything down and just makes me look like I work out a little. It's just a strong elastic really, doesn't' put any super amount of pressure on them... just presses them down a bit and spreads them out. I've been wearing one for like a year and a half, no disfiguration.
Don't be fooled by the fact that it's a fine mesh, it does not breathe well and it is HOT, and I mean HOT to wear it in the summer if you're not in air conditioning all day. Beware of that. it helps to wear a very light t-shirt underneath it as a liner, and to absorb and wick away sweat.
It sure does feel good though when you take it off and let the girls out after a long, hot day.
