Fastest way to cut out garment from shadowy and white background
Went to an interview yesterday and was given 20 minutes to work on something similar to this for a fashion company. It just stumped me. I usually like to take my time, put a layer mask on, select it with quick selection, or magic wand it, and even get the pen out and paint it away. But that usually takes me more than 20 minutes.
In a fast paced job, when someone shoves this on your pile, what's the quickest way of just selecting the garment?

Image wasn't this exactly but was near enough (there was even lace at the bottom!!) I had trouble with the selection of the background bleeding into the garment, and the greys messing it up. I wonder if you were to set the contrast to the highest settings to use as for selection, but I am still having issues with the whites and greys blending into each other.
I was kicking myself after the interview so I'd really appreciate some tips! Many thanks in advance!!
