How to put on a bra:
1) Select appropriate bra. This may vary depending on individual size (aka "endowedness"), style, occasion, clothing choice etc.
2) Hold bra by straps in front of body and carefully insert first one arm, then the other, into the straps so that cups are positioned in front of bosoms.
3) LEAN! Forward usually works best. Lean to enough of a degree to ensure all boobage is inserted firmly into cup. Again, degree of leaning depends on individual endowedness, or "boobage".
4) Scoop/fluff boobage in cups to ensure accurate positioning of boobage and maximum fillage of cups.
5) Wriggle/jiggle/yank. You may need to wriggle a little to feel comfortable. Jiggle the boobage to a final appropriate position. Yank the shoulder and back straps for maximum comfort.
6) Be proud of having accomplished one of the most overlooked but most important tasks of womanhood (unless you're Germaine Greer).
7) Take that boobage to the world. This often works best under an appropriate top/dress.
(this is how I do it anyway...)
