I think I'm going to make it for February! I was very tempted by a Stitch Fix "no styling fee" offer this month (my few, favorite items of clothing are from Stitch Fix), but I managed to not succumb to temptation so I'm feeling very empowered. I did buy my teenager new shoes over this past weekend, but he only had one pair of shoes (aside from football and rugby cleats, and dress shoes), and they were literally falling apart. I am counting it as a win, since my goal was to buy nothing for myself, and nothing for anyone else that wasn't a "need". Teenage boy has to have one pair of shoes for every day wear/running. We did shop around online after going to one store and found the same shoes he wanted for $25 cheaper elsewhere on sale, so even better.
I am going to stick with it for March. My only allowable purchases for myself this year are: a second pair of jeans if I get down to one (I wear jeans to work every single day, currently have 3 pairs that fit and aren't too ragged to wear to work), and a minimum amount of clothing in the next size down if I lose weight, after trying everything in my closet. I have a lot of clothing two sizes down...sigh. Pretty sure I am still safe to commit to March.
