Fingerless gloves are a staple for me - every year I get a $2 pair and snip off the tips for easier texting - but basic black gloves in general are a style classic.  Another style classic:  leather.  So it's no shocker that black leather gloves will always be a staple.  While you're (hopefully) resolving towards more sustainable style, consider a great pair of quality gloves.  Those cotton drugstore gloves are convenient, but not exactly fashionable, and I'm always misplacing and replacing pairs.  An awesome pair of leather gloves will not only serve you better in slushy wet weather, but are so stylish you won't let them out of your sight and lose them.

Black leather has had a resurgence with the fall 2008 goth trend, but it's not really surprising that black leather gloves are making a comeback.  Trendsetters are opting for more durable items that will last through the seasons - what material has a better reputation for durability than leather, which can actually improve with age.  Great leather gloves can be worn through frigid winters, obviously, but aren't out of place with a light spring outfit either.

With an otherwise feminine outfit, I see no reason why a simple, plain black leather glove can't look feminine and sophisticated, but lace and bows keep it girly if looking too 'hard' is a concern.  If you want to stay right on the cusp of trendy, slip your fingers into a pair of half gloves until summer kicks in.
