Soft, stretchy, and surprisingly supportive — this Free People bralette is my go-to for layering under tees and tanks. Comes in a bunch of colors, and the flexible sizing (S/M or M/L) makes it easy to find a comfy fit. Tagging it plus a few more soft bra and bralette options I like from the brand here: LTKFindsUnder50 LTKPetite LTKMidsize
