Dressing with Etiquette (Part V): Ladies Who Lunch

http://towandahistory.org/searchtopicresults.cfm?select=Leisure

Today's 5th installment in the series of Dressing With Etiquette, 1918 looks at the appropriate attire for an afternoon tea:

As hostess at an afternoon reception or luncheon one may wear an elaborate gown of the richest materials, with either long sleeves and high neck, or elbow sleeves and slightly low neck. As guest one may wear a walking suit, with pretty blouse, white gloves, and decorative hat. 

The usual dress for a formal breakfast is much the same as for a luncheon,- a pretty afternoon street costume, with a dainty blouse, gloves, and "picture" hat, which is not removed.  In summer, a gown of light material, such as organdie, muslin, or other soft goods, dainty and somewhat elaborate, is in good taste.  Hat and gloves are invariably worn with this gown if the affair is ceremonious.
