(cust is trying on a strapless bra)

EM: It's a bit big on the back... The cup looks ok so I get a 32f for you
Cust: ok
(EM gets it and then comes back, cust puts it on)
Cust: what size is this... Did you say a 32j?
EM: ... This one goes up to a h...
Cust: is this one a j
EM: it's a 32f
Cust: oh...
