I just ran into these two videos that set a record for most bras unhooked in a certain amount of time.

The first one sets a record of 42 double clasp bras unhooked through a t-shirt un 1 minute.

The second is a non official count, where the contestant unhooks 17 bras un 20 seconds. That could have been close to 51 in a minute. But in this case there is no t-shirt to make things difficult so is not clear which one is faster
