I have recently bought this. WAs dubious about tankini for the same reason as moondog says but the fold over knickers fold up to waist under the tankini so keeping a smooth line and the vest is a nice length and not too tight so v flattering to my apple shaped big tum! here
Have already got a one piece and, yes, it's quite a nice one (for me) but I have done the thing that I swore I wouldn;t do this year: leave it til the last minute then decide I HAVE to have a certain item and it will make all the difference to the holiday and this year it's a blinkin tankini. Please humour me I have PMT and am absolutely incapable of thinking straight.
The fold over knickers sound nice. reminds me of the ginormous jersey pregnancy trousers that I wore for both mine: you could wear them folded down or pulled up over your bump. I loved having my bump covered. These bottoms would obviously be covering something far less aesthetically pleasing but it would make me feel secure none the less. <mad>
I've just had this trouble and as I need lots of support found it really hard to find anything in stock. I ended up here and managed to get the Panache underwired one. Just hope it's ok and arrives before we go next Sunday!!
I've found the fat face tankini tops to be pretty long. Crap at links - but if you google fat face you should find it. They are also in all the heathrow (cept 5) and Gatwick terminals if you don't find anything beforehand.
