So Im big on fashion and I dont like always having to wear a bralette or have my bra showing, my mom said I couldnt go braless and I'm too big (Im a 34B) and I'd rather be braless that have an annoying strapless on.
Omg! I'm your sister bra size (32C) so we have similarly sized boobs. For me it wasn't as much not wanting to wear a bra, it was that I wear a lot of dainty tops that can't be worn with a bra. What I do if the outfit is something that's too close to my boobs to be worn compeltely unprotected is cross two bandaids over each of my nipples (the fabric parts covers the nipple, the sticky parts stick out in an X shape). It works perfectly for me because the pointy nipples are covered, which is the only part of going braless that is perhaps offensive in my opinion :)
Um well you CAN but due to a lack of support the weight of your breasts will exert pressure on your spine which could lead to back problems. Plus your nipples will be visible through most shirts and if you wear anything low-cut you'll basically be flashing your boobs whenever you bend over.
Invest in some pasties if you do not wish to have a bra on. That way you won't show through your shirts, but can still be comfortable. They also are called "petals" and you can order some cheap off of Amazon no problem.
