Well, ladies, I have been on hrt for the past 4 years, going on 5 at the end of November. Not only do your boobs grow, my clothes hang differently, especially around my leg area and I'm very much smoother in appearance, and long hair. I wear very loose dress shirts and slacks, but I always make it a habit to wear a windbreaker jacket. I also have long hair. Off work, I wear Hawaiian shirts and it does seem to hide my growth, but I'm pretty sure I'm a solid b, or tanner 3, at my age. Helps if I'm overweight, but only so much, since I'm tall too, at 5' 10". I wear a sleeveless white tshirt underneath(acts like a bra of sorts), over white vneck tshirt, then the dress shirt, which works pretty well, for most situations.
