Okay, so I finally caved and bought these Amazon Essentials camis after my old ones started looking like they'd been through a war. Got the 4-pack in white first to test - and wow, they're THICK! No more awkward bra-showing-through moments (as long as you wear nude/pink).
The fit is totally true to size for me. I'm 5'4" and the medium fits like it was made for me. Ended up ordering two more packs because hello? Twelve camis for the price of... well, way less than buying individually!
Love that these work for literally everything - sleeping, layering under sweaters, even light workouts. The V-neck is actually flattering (shocking for basics!) and they're long enough to stay tucked in.
Only thing? The white isn't pure white - it's more off-white. Not a dealbreaker for me since I mostly wear them under things, but heads up if you need bright white.
PS: The adjustable straps are a game-changer! Why don't all camis have this??
