It depends on what you like, styles you like, your size..
I wear all Victoria's Secret cotton thongs and love them. I hate Victoria's Secret bras because they are not in my size.
I do like matching sets so I have fun with the panties and my bras are black or nude.
I LOVE Wacoal bras (a little pricier but very durable). I do not like stitching, seams and padding in my bras, I am ample enough and Wacoal has the perfect bra for me which is a racer back with no liners and an under wire. I prefer my bras to be functional and well made.
I wash bras in cold delicate cycle and hang to dry and I wash the thongs with whichever load they go with for the cycle, darks or whites.
I don't have to worry about my monthly cycle because I had a hysterectomy about 13 yrs ago. YEAH!!!
