This $19 Bralette Was "Love at First Wear" — and It's 40% Off For Amazon Prime Day

I don't have big boobs in the slightest, but I have the world's widest rib cage, so bra shopping has never, ever been fun (not that it sounds very fun if you're well-endowed either, but I digress). Since my first training bra was purchased around the time I turned 12, I've hated wearing a bra at all. Like most bra wearers, I spend my days at work dreaming of that glorious moment I can strip down at home and fling my underwire death-trap across the room like a slingshot, allowing my girls to roam freely for the rest of the night. I thought I was destined to waste my existence, wishing it were the end of the day, until I found Calvin Klein's cotton bralettes.

Now, I'm not living under a rock; I'm not new to bralettes as a concept. I know there are a zillion out there, from lace-embellished options to those crafted in sweat-wicking material to stand up to workouts. But this Calvin Klein Modern Cotton Unlined Wireless Bralette in Black ($19, originally $30) is the one that's quickly become my holy grail, and I vow in front of all these witnesses to love it forever. Did I mention it's also marked down as part of the Amazon Prime Day sales, which only last until July 12? Trust me; you'll want to add this comfy bra to your digital shopping cart ASAP.

It all started with an Instagram photo (as most revelations these days do). I spotted my little cousin wearing one of these simple bras as a top (to go to the club, because she's young and hip and not the ripe mental age of 97, like myself). She looked so comfy, so I immediately texted her to ask where she got it while also subtly begging her to just pass hers on to me. She told me she got the bra at Urban Outfitters, so I visited its Instagram page, and wouldn't you know it, these bras were featured in two or three of its 10 most recent photos. I took that as a sign of a trend, urged myself to get out of bed early on a Saturday morning (OK, it was like, 11 a.m.), and drove straight to the store, where I purchased a CK bralette in black, to match my soul.

It was a deep and passionate connection from the first wear, and our whirlwind romance has only intensified since then. (I'm pretty sure my boyfriend suspects I have stronger feelings for these bras than I do for him.) Overflowing with excitement, I couldn't resist capturing the moment by snapping the photo above, joyfully sharing my newfound ecstasy over this remarkable bra with my Instagram followers. The comfort and support were perfect; the dream fusion of being held in just enough but also so free.

It's been approximately four glorious months since I embarked on this bralette journey (time truly flies when your bosom feels liberated). Since then, my collection has grown to include two more (white and gray because neutrals are life). I haven't missed a single day without donning one of them – except for one unfortunate occasion when I needed a strapless style. Let me tell you, as soon as I clasped myself into that restrictive contraption, I wanted to burst into tears. If you're anything like me, the moment of freedom that comes from swinging your bra over your head like a lasso after enduring hours of confinement is simply unparalleled. So why live as a prisoner any longer? Join me in this place of pure bliss, won't you?
