The sells down

After calculation, stocking etc..Turn out the bra selling it was not as I expected.Last month, we only able to sold out 50 set of bras, and I expected a minimum 60 sets (assuming 1 set daily and by two seller, although now we're all four seller). Really disappointing.
My cousin a.k.a partner can't focus in selling because she has computer store to look after and her toddler, Jamine, just started her kindy and still adjusting with her new baby sitter. My marketings are still new and very depend on me to explain to customer and I'm too full to take care all of them.
This week was worse, I didn't sold at all. I was busy designing for my new design project which was more demanding and my marketings, as usual, without me kept pushing them, they just lack down either.
The most obstacle in selling was, on the first look, people usually will reject to try on the bra, the common reason was: 'Aiyo, so ugly, no padding, no wire, the bra look like my mums, so old fashion, not sexy'. And the second rejection was: 'Hah! just apiece of cloth, why cost so expensive ?' And the third rejection was: 'What? Have to strip off to be measured? Can't measured with cloth on meh? Aiyo, no lah, ashame.'
I usually, explained to them patiently ,although with gritted teeth sometime, that even it may look old fashion, but full of benefit and advantage, and with wearing elling bra the right way, our breast will even look more sexier because it will reconstruct our breast shape and those natural shape that will show out behind our dress/ T-shirt, not factory molded fashion bra's pads.The price is cheap lah consider all services they will get. And without proper measurement, it will be useless to wear elling bra.
Mostly they will understood but when my marketing dealing with new customer alone, somehow they were not able to convinced. I need to re-training them. Gosh, wish I have more then 24 hours a day, so much to do.
I know that we need more marketing and training them to boost up the selling but seem we're busy to run our own business and having difficulty to divide our time.
Must figure something out ASAP or all will failed
