I learned this little lesson from a couple of Washington, D.C. drag queens back in my plus-size modeling days.
What you will need
a towel/ or sweater
First, and I cannot stress this enough. You must use your own rack. Barring that, use that of a willing friend. The best taped plans gang aft a-gley, as our friend Bobby Burns would say, when you try to lift and separate a stranger’s sweatermeat.
Secondly, unless you want your “crowning glories” to pop off like pen caps (is that creepy sounding? That’s creepy sounding right? I’m just trying to be delicate, but I guess that horse left the barn with sweatermeat.) you’ll need a nice fuzzy towel or sweater. You need the fuzzy sweater or towel to reduce the adhesive properties of the duct tape. If you forget to do this, it will End Badly and you will probably die.
Also, you should probably stretch first.
Tear two pieces of duct tape long enough to wrap across your torso from side to side. Place them sticky side down on the towel. These are the foundations of your foundation garment.
Tear two pieces of duct tape long enough to stretch from the underarm to the middle of the chest. These are your “underwires.” Tear each piece lengthwise so you will have four thin strips. Put those on the towel as well.
The assembly of the bra is more art than science, so you may have to winnie around a bit, but here are the general rules of application.
Leaning forward, place one of the long strips along your torso just under the bust line. This should give a bit of a heave to the whole bosom area. If you are applying the tape from the left to the right, lean a bit to the right and then to the left so that the gals are arranged for maximum cleave and minimum splooshy back fat.
Leaning forward and a bit to the left, apply one of the thin strips in a curve from under your arm –where your underwire would go– and pull snugly until the mammary in question is more or less where you feel it ought to be. Repeat for the right.
Apply the second long strip across your torso over and slightly above the first and add the final “underwire” strips in the same method as the first.
This might take a bit of fiddling, and as always, your cleavage may vary. If you’ve got a hard to wrangle rack you may end up using more tape, although, for structural integrity, I would not suggest using less.
To remove: hold the skin taut and peel back. It’s really not painful, as long as you remember to use that towel. Alternatively, take a shower.
Have fun, but be responsible! Oh, and there’s no use asking for a photo essay or diagram. I’m hopeless with a sketch pad and my dog can’t work a digital camera.
