Can I help you ?   I'd like to buy a skirt .   What style would you prefer ?   I like one with flowers on its brim .   Do you like this one ?   It seems too short .   What about this one ?   It looks nice . How much is it ?   70 yuan .   Is there any cheaper one ?   This one is only 50 yuan .   I think I'd better take that one you showed me just now . It is better than this one although this one is cheaper .   All right .   Here is the money .
