I have the Margo tee in both s and xs. They both work - depending on what kind of fit you want. I like to wear xs as a base layer and s as a tee on its own. I don’t have the long sleeve yet but I’d like to get it in a s. Fast shipping to Canada 🇨🇦 and duties included I sized up one size for the Pointelle tee. Regular size would be too small LTKsale LTKpetite LTKfall
