Hey Sun Country:
Maybe get a single pair of shorts and a matching shirt and wear it as your weight loss *show off* outfit. That way you won't spend much on clothes and can have one thing to really feel good in. If you are consistently losing weight, there is no point in buying many clothes (regardless of sales) in your current size. Next summer you won't need them anyway. If you know about what size you will be at 140, maybe buy an outfit or two for next summer since the stuff is on sale

I too have LOTS of skinny clothes left over from a few years ago, so as I lose weight, I just get to fit back into older clothing (or shorts that were so tight before it was laughable that I would even try to fit into them )
