A little tip on the fit of swimwear: swimsuits and bikinis should ideally be a little tighter when you try them on. The reason for this is that the material expands slightly in the water - if the garment is too loose at first, it may lose support later on. So if you are unsure whether your swimwear might look "too tight" when you try it on: In many cases, this is just right and ensures the perfect fit in the water.
