Unfortunately, it has been more and more difficult to find clothes for Slink Physique.
I have a Physique in one of my avatars too and I love this body on her, because I made her to have an athletic look. But because of this lack of clothes for Physique, I decided to change to Hourglass and it was the best decision for me. Although Slink Hourglass is a lot more curvy than Physique, they have some similarities, and that avatar already has the feet, hands, appliers, shoes, etc. So I worked a lot on her shape trying to get a similar appearance as the one she had with Physique and even she is no longer that athletic, I'm satisfied the way she looks now.
My advice is: try a demo, maybe you'll like the result.
