Victorias Secret quality has slipped a bit in the last few years and their fabrics seem to lose its elasticity towards the end of the day, that's why I really prefer
Soma.com, their styles just seem to fit better and are better made, they are not cheap but once in awhile the have a "7 pair for $35" sale which is a savings of over $70!!
I like their bikini and hipster styles that come with different lace trim options and nice colors

depending on the style I wear either a small or medium and they stay comfy all day long.
I've always been thankful I don't have much going on down "down there" so it's not to hard to hide the poor little thing
