[Problem] The purpose of the present invention is to provide a biological information measuring garment having excellent exterior design, and yet with high measurement accuracy.[Solution] A biological information measuring garment is provided with an electrode support portion which is joined to a garment body with an amount of freedom and which preferably has a covered-binding structure (looped structure), wherein the amount of freedom of the electrode support portion is set in a predetermined range such that, even when an electrode is in contact with the skin and in a semi-fixed state, the outer side of the garment can accommodate natural movements. In addition, a garment includes at least: a cup portion which covers the female breasts； and a front body, the garment further including on the inside thereof an electrode support portion provided with an electrode for biological information measurement. The cup portion, the front body, and the electrode support portion are sewn together at the same position, and a measuring device is disposed so as to be hidden between the garment and the electrode support portion, thus providing a structure preventing the measuring device from being seen from the outside.
