Make-up: My skin became very sensitive after starting hormones and doing laser and electrolysis. I found the only make-up my face would tolerate is Bare Minerals. It is a little pricey, but I love their products and they last all day and there is not that "caked on feeling." I also use a daily moisturizer on my face, Neutragena with 15 SPF, and Retin A on my nose to reduce the size of my pores at bedtime, and then also Neutragena nighttime anti-wrinkle cream at bedtime. I have learned to never let my face go unmoisturized.
Nails: Rimmel for my fingers, typically something cheaper (Covergirl or whatever is on sale) for my toes in the winter and Rimmel in the summer for the beach and sandals. I also take Biotin and Vitamin D and swear they cause my nails to be stronger and grow quicker.
Bras: My favorite brand is Maidenform, which fit me perfectly. I am a size 34B, leaning on 34C. I also own a few Victorias Secret bras, one from GAP Body (I really like), and a few from Aerie. For working out I wear a sports bra from Title Nine.
Underwear: I usually wear Victorias Secret cotton collection bikinis or hip huggers (size small). I wear Hanes boy shorts for my workouts/exercising.
