Good morning, and thank you for joining us. Also joining me remotely today are Sammy Aaron, our Vice Chairman and President; Wayne Miller, our Chief Operating Officer; Neal Nackman, our Chief Financial Officer; Jeff Goldfarb, Executive Vice President; and Priya Trivedi, Vice President of Investor Relations. As we are hosting this call remotely, please bear with us and stay on the call if we have technical difficulties, we'll be right back with you.
The coronavirus outbreak has become a national and worldwide crisis. Our top priority is to ensure the health and well-being of our employees. In that regard, we've closed all our retail stores and corporate offices. We continue to work remotely where appropriate to remain operational.
I want to remind you that one of our core competencies in our well-developed supply chain infrastructure -- is our well-developed supply chain infrastructure, and we are working to leverage our strong vendor relationships. As I mentioned during the tariff wars, we did not abandon these well-financed and loyal vendor relationships built over the past 40 years. It is these relationships that are providing us the ability to manage our receipt flow over this difficult time.
Based on current updates of factory operations in China and other affected areas, we now anticipate only minimal delays in production and in transit times. That said, sales for both our retail partners and our own retail stores are being impacted. This is a very fluid and evolving situation. We're in a daily contact with our retail partners and vendors. We will provide additional information when we report the results of our first quarter earnings in early June.
We continue to work towards the restructuring of our own retail operations, which would greatly reduce the number of stores and losses we're incurring. We see upside potential for the DKNY and Karl Lagerfeld Paris nameplate. Both businesses posted positive comparable sales for the fourth quarter and the full year. The effect of the coronavirus is negatively impacting sales. The new product for DKNY and Karl Lagerfeld developed and curated under our new leadership is working well.
Our e-commerce business for all of the brands are doing well, with DKNY and Karl Lagerfeld leading the way with strong double-digit sales increase. As soon as we finalize our restructuring plans, we'll report back to you. We're confident our strong wholesale business, along with a more streamlined retail operation, creates a solid foundation for continued growth and improved profits for the future.
Our success remains anchored by our 5 power brands: DKNY, Donna Karan, Calvin Klein, Tommy Hilfiger and Karl Lagerfeld. We have the flexibility and the ability bolstered by our strong financial condition to adjust and adapt to the challenges and opportunities that lie ahead.
Fiscal year 2020 was another year of growth for G-III. Calvin Klein, our largest brand, continuing to take market share. DKNY and Tommy Hilfiger both had strong growth, benefiting from expanded distribution with significant opportunities ahead.
This year, we've also broadened our product expertise in the denim category as we launched the collection under the CK Jeans brand. This coming year, we're adding comprehensive denim collections for 3 of our power brands: CK Jeans, Tommy Hilfiger Jeans and DKNY Jeans which will make us a significant player in the important denim space.
Now let's look at the full year and fourth quarter fiscal 2020 results. We reported another year of growth in net sales, adjusted EBITDA and non-GAAP net income per share. For the full fiscal year, net sales of our wholesale and retail segments were $3.16 billion, up 3% from last year's $3.08 billion. Importantly, the wholesale segment net sales grew over 5% to $2.86 billion from $2.72 billion. Our non-GAAP net income per diluted share was $3.19, up 12% from last year's $2.86. Our adjusted EBITDA for the year increased to $285 million, up 6% from last year's $271 million. Fourth quarter non-GAAP net income was $0.75 per diluted share, up 37% compared to $0.55 per diluted share in the fourth quarter last year.
Now let's turn to some details of our wholesale business. Our sales growth for the year was led by Tommy Hilfiger, DKNY and Calvin Klein. In the fourth quarter, net sales fell short of our expectations primarily due to the warmer weather during the important holiday selling season and in the month of January. This negatively impacted our sales of cold weather apparel, including outerwear. However, we were able to offset most of that impact of the net sales mix primarily through good expense controls and non-GAAP diluted earnings per share was above our guidance range.
Calvin Klein is our largest business, with net sales approaching $1.1 billion this past fiscal year. The brand remains a dominant resource in the women's apparel market. We were pleased with the soft launch of CK Jeans this past quarter. We believe we've built the right combination of fashion and basics into the line and will remain flexible to tweak the mix as we move forward.
Our Tommy Hilfiger business ended the past fiscal year with net sales of nearly $500 million, an increase of 25% from the past year. Although the fiscal for fourth quarter growth was impacted by the warmer weather, our Tommy Hilfiger business was up mid-single digits. Importantly, for the past fiscal year, the strong growth was broad-based across all categories.
Tommy Hilfiger Jeans line also launches this spring. As we continue to broaden our product offering and distribution, we remain confident that we can meaningfully grow and expand our Tommy Hilfiger business over the next several years.
Our Karl Lagerfeld wholesale business ended the fiscal year with net sales of just over $110 million only slightly up from the prior fiscal year, largely due to the changes at Lord & Taylor. For the Karl Lagerfeld brand, we continue to build the lifestyle appeal and will further work to expand product distribution.
Our own DKNY and Donna Karan brands registered another solid year with net sales growth of nearly 25%. These businesses now generate over $450 million in annual wholesale sales and licensing revenues and are a significant profit contributor to G-III.
This spring, we're introducing our new DKNY Jeans line with a soft launch. The line has been well received by our customers. For this past quarter and year, we saw strong sales increases in our DKNY international businesses, which include better department and specialty stores in Europe as well as distribution around the world. In February, we kicked off our spring 2020 advertising campaign for a second season with artist and global mega musician, Halsey. We'll continue to have a digital-first approach to our strategy, especially now, focusing our resources to increasing social media messaging to continue to engage and excite the consumers, keep the DKNY brand top of mind as we work to amplify the brand's awareness.
Licensing is another important part of our DKNY and Donna Karan business profile as it is a meaningful profit center -- profit driver of our business. We've created a solid licensing base with world class partners. Overall, we're very pleased with the development of DKNY and Donna Karan businesses. I'll now pass it to Neal for a detailed discussion of our fourth quarter results. Neal?
