Best speedo for sexy tan lines

[Speedo_z]

Hi Guys
Well in the UK it's getting to the time when I use a sunbed to keep up my tan.
Obviously on a sunbed, one can wear something a little more skimpy than in the local pool to do laps.
So which brand and style of speedos gives the best tan lines?
What do you think and what do you use?

I guess the narrower the sides, the better.

It's important you wear the same suit every time you lay out. And you need to position the suit in the same place. If you wear different suits, the edge lines will become "fuzzy" as different sections of skin are exposed.
