mikey_101 saidHow are these sized?
I have been busy buidling and toning my body for the last 6 months, and have a beach holiday planned.
Want to buy some tight speedos to maximise the tan, and show by body to its advantage.
I'm a 31 waist, and 34 hips.... which size speedos are best?
I'm not sure how fitted or tight they are.
Go to a store that will let you try them on, and many dressing rooms will have a full-length mirror so you can see their fit without needing to step outside the booth. Start with one closest to your measured waist size, then try the next smaller and larger for comparison. Bring a friend along, too. If the brand only has sizes marked S, M, L, XL, then for your waist try the S & M (no pun). I don't think you'd be an XS (extra small), more a boys size, even in the less rotund UK, as compared to the porky US.
A problem with smaller is that, while the fabric is elasticized and will stretch, the tighter waistband will compress your skin, and give the illusion you are overweight at the stomach. Watch for that effect when you try them on. Smaller will also cause more definition of your dick to show through the fabric, or as we used to say: "So tight you can tell his religion." Whether you want that obvious appearance or not is of course your call.
If you were planning to buy online then I'd look to see if they have a sizing guide, and follow that. Even if you do try suits in a store, but buy online, different brands and models will vary in their fit, unless you're getting exactly the same suit you tried on. The Speedo brand, however, is fairly consistent in sizing, provided you stay within type, like a tank bikini or a square-cut.
