Bit skimpy

Originally posted on marksandspencer.mom (UK)

I bought a pair of these last year with a matching bikini top and loved them. This year's bottoms have a bit less fabric, I was hoping for the same amount of bottom coverage...a bit disappointed as we don't all want our swimwear up our bottoms. Maybe there could be two styles on offer?

Nice basics

Good basic bikini bottoms - well made and sizing as expected. Nice to have option to choose sizing of tops and bottoms individually rather than a set

Must have basic for everyone

I have this bikini bottom in lots of colours. Great quality for the price, and covers my curves wonderful. I’m a size 12 on the bottom but the size 10 fits me as I want (and no ‘thong style bottoms, hurrah)

No, I don't recommend this

Well made, without the very close cut of fabric to seams of other manufacturers
