Okay, so I finally caved and bought the CK Constant Convertible Bra after seeing it everywhere. And wow - this thing is LEGIT comfortable. Like, 'forgot I'm wearing a bra' comfortable.
The fabric is crazy soft but still gives great support. The convertible straps are actually useful (not just a gimmick!) - I've worn it three different ways already this week.
Pro tip: Size up if you're between sizes. I'm usually a 34C but went with 36B and the fit is perfect. The underwire doesn't stab my ribs like most bras do.
Only complaint? The price tag hurts a bit, but honestly the quality justifies it. This bra has survived multiple washes without losing shape or getting those weird little fabric pills.
10/10 would recommend to anyone who hates bras but still needs to wear them. It's like the Goldilocks of lingerie - not too tight, not too loose, just right.
