Is the Calvin Klein Modern Cotton Thong worth it?

If you want the soft cotton-modal feel and the logo waistband, yes. At $19.99 at eBay as of November 5, 2026, it is a fair single-pair price for a branded basic, though multipacks cost less per pair.

How does it fit compared with other Calvin Klein thongs?

It fits true to size with a medium rise and minimal rear coverage. If you are between sizes, the elastane content gives some stretch, but most shoppers stick with their usual size.

53% cotton, 35% modal and 12% elastane, with a cotton gusset. Machine wash and tumble dry low.

Is this the same as the Modern Cotton bikini or boyshort?

No. It uses the same fabric and waistband as the rest of the Modern Cotton line, but the cut is a thong with minimal rear coverage.

When is the best time to buy it?

Prices on single pairs move little. Watch for multipacks or seasonal sales, and compare the two new listings; the lowest seen is $19.99 at eBay as of November 5, 2026.
