Advice re padded cycling undershorts please

Why don't you just buy a pair of normal cycling shorts and wear them under your shorts? The shortest I could find were these gore ones. Any shorter and your inner thigh/leg will rub on the seat which will blister after awhile

Hello
My advice, is that although padded shorts are useful, the best protection is to 'prepare' your bottom (!), through lots of cycling. Then its get used to it, so to speak. Obviously do still use padded shorts, but it will be a disaster if you rely on them! Other than that, I've just gone to sports direct and bought relatively cheap ones, which appear fine. I've got a long pair and a short pair, for different weather eventualities. Most short ones will appear under your over-shorts, but everyone's will, don't worry! (unless you are any good at sewing of course).
Have a wonderful trip.. I'm going in 10 days cycling in central america...
If you're not that used to cycling, my advice is spend money on a couple of decent pairs! I strongly recommend the ones with gel padding. It really makes a difference. I have short legs too, although I don't wear overshorts. you can always roll the end of the leg up if you're worried about them being too long but (a) no one will care what you look like and (b) it's quite trendy anyway to have the cycle shorts poking out of the bottom of the leg of your normal shorts :-)
Seriously, my all time favourite (and I've tried a LOT) are these: http://www.wiggle.co.uk/sugoi-ladies-rs-cycling-short/
expensive but worth every penny. I think they're discontinued on Wiggle but you can still get similar other Sugoi ones. Or look elsewhere. Altura do some good ones too but look for the ones with gel. Everyone is different in what feels comfortable for them though. I also recommend using some chamois cream (you can find it on Wiggle, I use Butt Butt'r). You can also use Vaseline or Sudocreme, in the worst case.
And most importantly, don't wear underwear underneath your cycling shorts (amazingly, many people do not know this!) - otherwise you get friction. Trust me on that, it may seem weird but it's much better without. And even more importantly, try to do some cycling beforehand to prepare your body, even if it's just a few spin classes in your gym. Have fun.
Def no undies and get yourself some chamois cream as well. This is a good one but there are loads of different ones around.
