At any rate I would recommend that you spring for at least one pair of good quality bike shorts. Have a look at what TE carries - you don't need the absolutely top-notch Assos ones, but good bike shorts are quite pricey - and worth every penny. Make sure you get a pair that fits well, they should be so snug that the chamois cannot smoosh around or bunch up. If this means that the leg or waist openings bind, you need another brand with another type of fit.
Do a search here on "favourite shorts", but bear in mind that we have all kinds of body types here and will have different favourites. By all accounts TE gives excellent customer service, so try giving them a call.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
