[Kaderin Triste]

I have the opposite boob issue. Mine are super small, so it's hard to find shirts that fit my shoulders without being too baggy in the chest (bending over without holding onto the shirt to prevent anyone being able to see all the way down to my stomach is dangerous) seriously, even just basic v-neck tees can be pretty revealing if I don't hold on when I bend/lean over, and pretty much any wrap style anything is a huge no. I've never tried formal dress shirts or blouses just because I haven't ever found any that I like yet. I mean, white is always super translucent, I hate flowery designs, and stripes and all that, and definitely no to pink anything, which pretty much leaves nothing.
I don't think I've ever had quite the issue you do with "knee length" skirts. At least based on your comment of "too short", which makes me think maybe like they hit mid-thigh instead?
Most anything is listed as knee-length for me generally comes close to the knees at least. Not usually quite long enougb, but not so short that they cause any real issues.

I dunno, maybe I'm just too picky or not adventurous enough; too boring with my clothes. I've tried some "body-con" style dresses and they weren't terrible, though I need to wear leggings or tights with them just to help control my butt, thighs, and stomach some. Most of the time I'm just boring t-shirts and maxi skirts jeans depending on what job(s) I have any given day.
