TSW Mixit Top is definitely a summer time favorite. I've made it three times now, so it goes pretty quickly.
I have made it in white pique, purple rayon Asian print, and now this deep rose/red cotton print. It is very loose-fitting except through the shoulders.
The pattern also includes a tank top. I like the general shape of it, but it has no bust darts, which leads to some bunching under my arms. I think the CLD hearts 'a' flutter tank may be a better one for me.
