Well, in most cases, no one will really see your undies unless you are wanting to be flirtatious, but if there is an instance where someone will see them then you just want to be sure to go with something that has full coverage. That means no lacy thongs, and no lacy boy-shorts. The boy-shorts may sound like they have more coverage, but they really do not because they cover a lot of your hips, but not much of your bottom. To be sure that you have enough coverage you also want to make sure that the panties only have lace trim, and are not lace all over since lace is very see through. You can actually get really cute sets of undies that fit this description at Target.
