Hi. I got engaged to my girlfriend this summer and we are getting married next year. Some both of us are overweight and want to lose it. We made a deal to get down to our as close as we can to our goal weight. Mine being 80 kg and he's being 47. It has gone well so far and I have gone from 125 to 111kg.
Now this week I noticed that my pants that I wear are getting a bit lose. So i have to pull them up all the time. I have a belt that I can use to keep them up but I started to think of how I should do in the future. So my question is. Is it better to buy clothes like pants and shorts while I drop in weight? Or should I wait until I reach my goal weight?
<bot>: is it better to buy new clothes as you lose weight? Or should I wait until I get to where I want to be?
