I've had to search out a couple of discreet wardrobe enhancements. Maybe you need them too?
Sheer t-shirts mean showing more breast features than I want. When I tried one of those foam-cup bras it lept out of my drawer like a demented stuffed animal and felt stiff and unnatural on.
So I've ordered a $6 pack of Fashion Forms Silicone Gel Petals from Bare Necessities, which I can tuck in my bra; I hope they work.
If the petals prove insufficient, Wacoal (one of my favourite bra brands) makes a foam cup that slides in any bra; they are sized, and cost $10 from the same source.
I don't mind showing toe cleavage but found the Jackie O ballerina flats I bought at Nordstrom scarily insufficient in the arch.
These FootSmart leather 3/4 arch insoles give blessed, breathable support.
