In a Dilemma

I have a dilemma and I need your help. I just got the new Long Tall Sally Catalogue. In it is this suit. I wear suits for work and only have one that really fits properly (sleeves the right length, jacket waist at the right height etc), because it was purchased from Long Tall Sally. I have others that are almost right and look OK on, but they don’t feel as good as the one from LTS. So now I really want a new suit that fits properly. Add to that the fact that if I buy now, I can get a 2nd pair of trousers or a skirt half price. I would go for the bootcut trousers and the pencil skirt, in black. The jacket is £65 and the bottoms are £35 (so the second one would be £17.50 – bargain!). But that’s a total of (tries to add up in head!)…erm…£117.50? (Is that right? Really, my maths is atrocious!) So, what should I do?!! To buy or not to buy, that is the question!
