Solo cups are based on US sizing, but they are very generous. If you wear US-sized bras, order the cup size you typically wear. If you prefer UK-sized bras, consider the following before placing your order:
First, I really wouldn't recommend this top for anyone over a 34 band. While this style can technically accommodate any band size, the back is an adjustable string that doesn't provide much support for fuller busts, and it can become uncomfortable after a while. If you have a difficult time getting a band small and firm enough to stay in place (a common problem for women in the 26-30 band range), then you will probably love this top!
Again, these cups are very generous. A stated D cup should accommodate up to a DD cup size, and a stated DD cup should accommodate from about an E to F UK cup size. Fuller sizes are estimated, and depend a lot on your breast shape/fullness. A stated E cup should accommodate from UK FF-G cup size. A stated F cup should accommodate from UK GG-H cup sizes.
If you have very soft breasts, you should note that Solo is a plunge style. You may find a better fit in a Panache or Freya style if you normally have problems with your softer breast tissue sliding or scooting out of plunge styles, or if you have a lot of side tissue.
The Body Glove Smoothies Solo Bikini Top 3950615D has underwire to give support combined with removable soft cups that can be left in for modesty and shape or removed to provide a more form fitting bikini top. The adjustable strap can be worn crossed or straight in the back. This Solo bikini top comes in beautiful colors that can mix and match with your favorite swim bottoms to look bold and sporty for your day in the sun.
