I have to admit, I'm deeply confused as to Bianca's presence in the Final now. It was already apparent that her idea was not quite as unique as she seemed to think, but last night really seemed to expose her BP as fantasy.
1) Tights will not sell at £35, at least not 'natural' ones. I accept Bianca was going for a high profit margin, but that only works if people actually buy the product. As evidenced by her later price drops, £35 was less 'Premium' and more 'Daylight Robbery', and to me at least it showed her in a very poor light.
2) The huge number of variations of the product would make them a nightmare for retailers to buy in, and the whole concept of perfect colour-matching is ill-suited to an online business. The whole USP is flawed IMO.
3) £250k was never, ever going to be enough investment for this BP - don't forget, Bianca had originally wanted even more products, but changed her mind after the interviews. Roisin was sacked partly because she would have run out of money very quickly - I honestly believe Bianca would have done the same just as quickly. The woman at the trade show was adamant that True Skin had to be a massive, international product - did LS really think that was achievable with a quarter million pound start-up?
I've nothing against Bianca personally - her pricing strategy apart, she comes across as a level-headed, pleasant woman and I hope she is very successful. I simply don't understand how her BP was considered suitable - although that could be more the fault of the show itself and its restrictions, rather than Bianca herself...
