Clothing quite depends on luck. To counter clothing as starting, the most effective way is to meld five different colors as soon as possible. Four colors have already stopped your opponents much. Just let him get achievement 1 or even 2, but avoid him to get achievement 3.
However, if you really cannot draw different colors, you may just scream. It is sad that I had faced my opponent using clothing with five top cards, and I had drew all yellow and purple cards without other colors.
Teching up is a good strategy. You may make it by Maths,the most simple way, or by others such as experiment, astronomy, atomic theory, etc. Those cards can help you directly draw a card one age higher. Some others may be democracy + encyclopedia, education may make you teching up even higher, but more difficult to control.
It may not be a good idea to teching up to age 10 if your opponent score too many score in a fast pace. For me, I may just teching up to age 7 to find combustion or lightning to help you to get higher achievements before your opponent getting them, or up to age 8 to find mass media or rocketry to return all your opponents score.
