Does anybody know what font is used in this t-shirt merch? It's from Beyonce's merch line. I thought it had a very interesting 'E' and 'A' crossbar, but can't seem to locate the name of it. 

The pairs of 'A's, 'D's and 'S's are different, so it's most likely hand crafted.

Ah thought so, thank you!

It feels like someone arranged the (actual or virtual) pearls on top of a serif font, but because the pearls are so large, the result is very far away from the original outline and it almost doesn’t matter anymore what the original font was. 

Almost purely based on the first |A|, perhaps they started with ITC Benguiat.
