Sizing Up

Finally, you are making progress with your weight loss goals and all excited about fitting into those clothes you had before the weight gain, so its only fair for one to wonder why the svelte looking sales associate is recommending you go one size up, if you prefer the tshirt in a ladies cut.

Taking a deep breath you gather yourself and manage to ask her "why the recommendation to go up a size or two?

It's not you. It's the tshirt cut.
A Unisex shirt is not as fitted as a Ladies t-shirt cut.
