Tightness in the cup might equal tight in the armpit area too possibly compromising lymph flow esp if wearing for the most part of the day.
I try to always wear my bras loose allowing for free circulation mostly on the lymph area. Don't want to trap any toxins in that area. And if you want more growth you want free flowing circulation. Something I never did. Always wearing too tight too small bras. Hope that helps with part of your question.

On another note.. What beautiful $@@&($$ bosoms you have. Am envious

I occasionally wear a sports bra if i have to wear tight clothing in public,, because i cant have cones showing,through my t-shirts,, i live in a small rural town lol,,, (But that's about as tight as that kind of wear gets.) The other clothes/bras i mentioned are on for very little time, some are almost painful to get on so i thought i should ask.

As for your compliment
Your a doll Ella ,,thanks a lot,, Being a biological male, Im still kinda surprised at peoples response to them.

My companion (a lady my age,) jokes with me a lot about (her prodigious whisker growth, and my big breasts,,) (I just tell her if times get too rough we'll just look for an old school carnival that needs a new act),lol
