I ordered these in m (5'8" 140 lbs.) and they are tts: they fit well and are neither tight nor loose. the issue that i have with them (and the reason that i sent them back) is that the material, although comfortable, is completely transparent; if i were to try to run out to get the mail in these, the whole neighborhood would essentially see me bottomless! furthermore, these are not white but off-white (and quite a yellowy off-white, at that), so these loungers don't look as cute with the feature
