Can a woman with a chest wear a sublimated top?

I may not be a lot of help as I had to look up what "sublimated" meant :) It's also hard to judge without a picture of the image or pattern on the top. That being said, here are my thoughts (with a lot of questions).

Ignoring the pattern, does the shape of the shirt suit you? If it does, that's a plus.

Is the focus of the pattern on the chest or elsewhere? if the pattern draws your eye to your chest, it will make that area look bigger. You could either accept or reject it on that basis or use other clothes to balance out your shape - a strongly or brightly coloured bottom (pants or skirt, or even long boots) which can draw the eye and create balance.

Also if the pattern is asymmetrical that will reduce the focus and actually create a slimming effect.

You may love the shirt but does it work for you? Will you feel happy and confident wearing it? If it doesn't then give it a miss.

I seem to have given more questions than answers but hope i have helped a little.
