What underwear to wear?

What underwear to wear? It's easy for guys, they just pick a pair of shorts and that's it! But for us women it is a whole differtent story. Your bra needs to be comfortable but you might also want it to match your knickers. Then you've found a matching lingerie set but then there might be the problem of visible panty lines if you wear that skinny jeans.. Or you find out that your bra has the wrong color for that shirt.. so many things to take into account..
