only, well done on the weightloss, and yes I'd say that size 15 goal is achievable.
Boobz, sounds like a good decision, to give up the regime you hated. Amongst the many things I've read recently about exercise was an article saying that exercise is totally counterproductive if you are hating every second and/or doing it with a "punishment" mentality, as it's just going to raise cortisol levels, with no good physical or mental results.
Re exercise wear, I live near a Nike factory outlet store so it's an obvious choice for me - and it always amuses me at the gym, that pretty much everyone there is in head-to-toe Nike!
Purple, hope you feel better soon. We have all had a horrible cough/blocked sinus bug in our house, which has lingered and lingered. 
I exercised x6 last week (mixture of stuff), but yet to get going this week... Need to find some motivation!
Waves to everyone else, good work all.
