The Thigh Society code at the top of the page takes 18% off your order, and that is the headline offer here. It is a site only promo code and is best for you when you are buying multiple items or higher value pieces where a straight percent discount beats single item sale prices.
Small single item buys under $45. If you are buying one of the marked deals such as The Cooling at $39 or The Cotton at $39, the stand alone deal price is usually the cheapest route because the deal price cannot be combined with codes. For example, on The Cooling at $39 the $39 deal costs $39, while the 18% code would reduce $39 to $31.98, so the code actually saves more in that case; use the 18% code for single items priced $39 (18% off gives $31.98, you save $7.02). On The Cotton when it is $44, the code reduces $44 to $36.08, saving $7.92 compared with paying $44 for the deal item.
Everyday shopping between $40 and $65. For carts in this range the 18% code at the top is typically best. On a $60 order, for example, the 18% code takes $10.80 off and leaves $49.20. The 15% codes will leave you paying $51.00 on the same $60, so the 18% code saves more.
Orders over $65 where you want free shipping. If your subtotal before any code is over $65 you get free shipping. Use the 18% code if the percent saving still leaves a lower total than combining a smaller percent and paying shipping. On a $100 order, 18% off takes $18, leaving $82. A 15% code leaves $85, so the 18% code is better.
Buying multiple shorts or bundles. The buy 3 get the 4th free deal applies automatically at checkout for selected styles when you purchase four or more eligible items and is limited to selected styles. Because that deal reduces the unit cost of four items, compare the per item price after the automatic reduction with what the 18% code would leave you. The free delicates wash bag is given when you buy two shorts and cannot be combined with other offers if those other offers say so.
Our records show 10 offers listed for the brand in the 12 months to October 2026, with percentage codes five times in that period. The biggest percent in that window was 18% off and the typical percent was 15% off. Our team ran five checkout tests across five offers in the 12 months to October 2026.
If you must choose, take whichever option gives the lower total at checkout. Note that several deal lines explicitly say they cannot be used with any other offers, so you cannot combine those deal prices with a code; otherwise apply the single code that gives the largest reduction to your cart total.
