The Bralette Co. パッド入りホルターネック

I sized up to a large based on the chart and the padding sits smooth under a thin tee, no weird bumps. Wore it under a backless top all night and the halter tie never dug into my neck.

The halter straps actually stay put all day, which I didn't expect from a bralette. I'm a 34B and the small fits perfectly with just enough padding for coverage under thin shirts.

Finally a padded bralette that doesn't flatten me out. The padding gives just enough coverage under thin summer tops, and the halter tie actually stays put instead of digging in. I sized into the M per the chart and it fits true.
