How much does a Lane Bryant manager make?

Depends on where in the country you live and want to work, and what position you are referring to, and most importantly...experience.
The management positions are: Store Sales Manager, Assistant Sales Manager, Full-time Key holder, Part-time key holder, relief key holder.

Store Sales managers are salary only, not sure what they make
Assistant managers are only in larger locations
Full-time key holders range from 9-12 and hour in most places
Part time from 8-11 and hour, again in most places
and relief key holders are between 7-10

this is just an estimate, it all depends on the experience you have in management and the area and sales volume of the store.
