Genuinely confused for a minute thinking, "When did I post a reply to this post?", bc this is 100% my experience too and why I do freelance now lmao! I love having the freedom to take a deep breath and go for a walk for 3 hours and/or watch some comfort episodes to calm myself down before I have to reply to some bs emails haha.
For me it's tighter than a sports bra, unfortunately!
If you have the means, I definitely suggest getting one your size and another one that's one size bigger (e.g., getting one L and one XL). That way, you have an option depending what you want to do that day and wear the one that's more appropriate for the day. For example, I use my size when I'm just going out to the mall or for a walk, but I use the bigger one when I'm going to a crowded concert or doing some light exercise.
OP's "They know" refer to how the dog knows the trans woman is a woman.
Not every post is about you.
