I am in UNLESS I make enough success in the "lose weight 2018" challenge. If I get to the point where I have zero bras or swimsuits that fit, I'll have to buy those, but 2 of each, period. I would have to lose probably 20 pounds for that to be an issue though, so until that happens, I am in. Also, I have to have 2 pairs of jeans that fit (all I currently have at the moment), so if I have a casualty and only have 1, that's a non-starter for my job, since I wear jeans every day. If I lose SOME of the weight I have jeans a size down that should fit though. And then plenty of jeans (and everything except swimsuits and bras) 2 sizes down, which is the goal.
I tried to do the no clothes 2017 but failed. I did NOT fail as badly as I have in previous years so I feel like I made really good progress there. So, count me in until I have nothing that fits!! Honestly, if I really get these damned 20 pounds off and need to buy new swimwear, I will gleefully do so.
