Small busts
If you have an A-cup size, you have a smaller bust. A button-up blouse is a core basic in any closet and is a no-fail outfit formula that is also very flattering for ladies with smaller busts and anyone, really. A white button-up blouse styled with jeans and pointed heels will most definitely freshen up your 9-to-5 look. You can also go for relaxed stylish styling with a head-to-toe black look, pairing a black button-up blouse with some black slouchy pants. Also when layered, under or over, the versatility of a button-up is unmatched.
