Mid-Way Rewards and Expensive Pants

It was suggested a bit ago that I work on developing some mini-goals for both targets and rewards along the way.

I thought of something last week that I put in my mind as a 'half way' reward:

When I hit 15 pounds (which I hope to be by Christmas, but we'll see!) I'd like to treat myself to a cute outfit from lululemon. I don't any yet, and figure this would be a great reward.

Do you know lululemon? They're expensive as hell. Like, shockingly expensive. So, are they worth it?

People I know who have them love them. Reviews I've read rave. They usually mention:

• Extremely well made - better than any other brand out there
  
• Fit very well (they come in even numbered sizes, rather than SML, so you can get a better fit)
• VERY supportive bra tops for girls of my particular sveltitude
• Free alterations on pants (for girls of my particular shortitude)
• Rumor has it, they make your ass look amazing. I don't think that's the category I'll be hunting for in my particular size, but it's nice to know it's out there.

Why not make this a 10 pound goal?Yes, I've done well so far. Here's the thing: They only sell sizes up to a 12 (though 14 appears on their size chart, I don't see them offered anywhere). I'm JUST fitting back into 12's again, and I want to make sure I'm much more confidently resident there (if not a 10!) before I lay down $100 for some yoga pants or something.

Do you have any lululemon? what are your thoughts? What do you think of this as a mid-way-to-goal reward?

Thanks for reading!
