Soft Cup Bra: a bra without an underwire. Use the tips in this BN article to find out what kind of cup connector is right for your shape.
Sports Bra: provides additional support to breasts during physical exercise; is not limited to lively activity. Sturdier than typical bras, sports bras minimize breast movement, alleviate discomfort, and reduce potential damage to chest ligaments. A front-closing style with a compression, seamless cup is often worn by women following breast surgical procedures. (Tip: You'll need a comfortable, supportive bra to wear immediately after breast surgery. Hospital staff won't necessarily tell you this. Minimizing drag on the stitches reduces pain levels.)
Shelf-Bra: a close-fitting camisole or cropped tank top made of stretch knit. The bust is lined with a layer held under your breasts with a band of elastic.
Stretch Undershirt or Camisole: extremely comfortable because it doesn't press or alter your shape; provides an extra layer under transparent shirts. The shape of your breasts and how your nipples respond to air temperature will depend on whether this garment meets your modesty requirements.
