She wore a tight-fitting jacket, dark olive velvet, and a cloth skirt, both heavily trimmed with sable, a beaver hat, with an ostrich feather, which made a sweeping curve round the brim, and caressed the coil of golden-brown hair at the back of the small head. The costume, which was faintly suggestive of a hunting party at Fontainebleau or St. Germains, became the tall finely moulded figure to admiration. Nobody could doubt for an instant that Mrs. Tregonell was dressed for effect, and was determined to get full value out of her beauty. The neat tailor gown and simple little cloth toque of the past, had given way to a costly and elaborate costume, in which every detail marked the careful study of the coquette who lives only to be admired. Dopsy and Mopsy felt a natural pang of envy as they scrutinized the quality of the cloth and calculated the cost of the fur; but they consoled themselves with the conviction that there was a bewitching Kate Greenaway quaintness in their own flimsy garments which made up for the poverty of the stuff, and the doubtful finish of home dressmaking. A bunch of crimson poppies on Mopsy's shoulder, a cornflower in Dopsy's hat, made vivid gleams of colour upon their brown merino frocks, while the freshness of their saffron-tinted Toby frills was undeniable. Sleeves short and tight, and ten-buttoned Swedish gloves, made up a toilet which Dopsy and Mopsy had believed to be æsthetically perfect, until they compared it with Christabel's rich and picturesque attire. The St. Aubyn girls were not less conscious of the superiority of Mrs. Tregonell's appearance, but they were resigned to the inevitable. How could a meagre quarterly allowance, doled out by an unwilling father, stand against a wife's unlimited power of running up bills. And here was a woman who had a fortune of her own to squander as she pleased, without anybody's leave or license. Secure in the severity of slate-coloured serges made by a West-End tailor, with hats to match, and the best boots and gloves that money could buy, the St. Aubyn girls affected to despise Christabel's olive velvet and sable tails. "It's the worst possible form to dress like that for a country ramble," murmured Emily to Clara. "Of course. But the country's about the only place where she could venture to wear such clothes," replied Clara: "she'd be laughed at in London." "Well, I don't know: there were some rather loud get-ups in the Park last season," said Emily. "It's really absurd the way married women out-dress girls." Once clear of the avenue Mrs. Tregonell and her guests arranged themselves upon the Darwinian principle of natural selection.
