How to dress when playing tennis in winter?

I just started tennis lessons (I mean I’ve had about 5-6 lessons) & I usually wear the classic skimpy tennis skirts & dresses you see girls wearing in tennis matches. But winter is getting closer & closer & since it’s freezing here, I think I’d catch a cold if I wore those. What should I wear? Wearing a tracksuit or a big baggy sweater just doesn’t seem right since all girls I’ve seen play tennis wear either dresses or skirts. Thanks in advance!

By products I mean the following:
volleyball
shoes
jersey
shorts
pads
socks

Also,where can I get these products?

I would also like to know this: How are volleyball shorts and jerseys supposed to fit?

Sorry for so many questions.
Thanks In Advance!

My husband and I are getting interested in golf and we would like to know what the dress code is for golf courses during the summer.

Thanks in advance.

Volleyball?

I am certainly interested in trying out for a local volleyball team in January. I have had a couple years previous experience, but I haven’t actually played in a long time. What are some things I can do to get in shape and prepared for volleyball to make the team? Thanks in advance for your help!
