I agree with Jamie. If I had a helper, I would give her a budget and let her shop on her own. If she isn't familiar with Chinese customs and traditions then perhaps you could brief her about the do's and dont's so she can avoid getting those. It is said that shopping destresses a woman so this might help relieve some of her home sick she might be feeling since she has left home for so long.
My helper is more conservative. So she prefers t-shirts than other fanciful tops. I seldom buy bottoms for them. As for shoes, mostly sandals which are comfortable and she can wear out on her off days.
Why not let her choose her own clothes during her off day? I would suggest stylish yet practical clothes. Maybe a comfortable blouse with a nice pair of jeans as well as a pair of flats?
thanks
