The exact ones I got seem to be out of stock right now (https://a.co/d/cBeQUL2) but I found that they have space in them for inserts and I got a multi pack of padded inserts (like these: https://a.co/d/iKFhtq3) also and just put several in each, and that worked well enough for me. I don’t pass at all so it was mostly just for myself so it may not work for you, I don’t know. But that’s what I have done in the past.
I don’t know what you mean by look weird - on me when I look down I just feel flat-chested. But I have a different one without pads and it feels quite nice and quite comfortable.
Also I tried regular back and racer back and just happened to find the latter more comfortable. I think it’s just about what fits your body the best. I don’t have a lot of experience though. Probably others would have better advice.
Like through clothes or the product itself is visible and mistook for breast?
Because you may be talking about adhesive chicken cutlets but if you just mean bog standard stuffing fill the toes of pantyhose with lentils and tie them off.
