What is clothes shopping like for conjoined twins?

While Abby is seen as the "outspoken" sister and will always win the argument about what they are going to wear, Brittany says her twin is also much more of a "homebody," whereas she prefers going out.

There are other differences too. Brittany is scared of heights, whereas Abby is not. Abby is interested in maths and science, while Brittany prefers the arts."

How can they clothes-shop? Don't special clothes need to be made for them?

Cannot begin to imagine the complications that dating/relationships must present...

Eeeee.  Aside from the obvious two personalities/once body challenge, I wonder if two personalities/two hearts is easier than two two personalities/one heart.
